  1. IMG_7525 2.heic.pdfIMG_7525 2.heic.pdfIMG_7525 2.heic.pdfMaking a move to Pro Audio so beginning the process of selling on my current equipment. First out of the gate are the Plinius SA Reference and Allnic L5000 preamp with upgraded KR Audio PLINIUS SA-Reference Power Amplifier £6000 The award winning SA Reference amplifier paints a seamless sonic picture from the most tuneful and accurate bass to a sweet, extended top end. Designed to work as either a monoblock, or a stereo amplifier. They are truly a masterpiece of design and they display the very best craftsmanship in their build quality. As a bridged monoblock the SA-Reference will exceed 1kW of pure balanced amplification and in balanced XLR mode operates as a true balanced amplifier from input to output. Premium components have been used throughout and Class A operation is maintained to over 100 Watts per Channel while 300 Watts is available in both Class A and Class AB stereo mode. When you purchase a Plinius SA Reference amplifier you are among a very select group of audio enthusiasts that have realised the dream of owning a product that delivers sonic clarity and aesthetic finish combined with extraordinary build quality. The team at Plinius are immensely proud every time one of these units leaves the factory. ALLNIC L5000 £6000 The Allnic L-5000 DHT is the world’s first commercially produced, pure DHT preamplifier. Currently, the L-5000 DHT’s large output tubes are very rare items, produced many decades ago. Allnic has been able to secure a limited number of these valves, enough to produce an also limited number of the L-5000 DHT preamplifier. ONLY A LIMITED NUMBER OF UNITS OF THIS DESIGN WILL BE MADE. The L-5000 DHT has the following features: Line output transformer coupling – The L-5000 DHT is “transformer coupled”. In tube amp circuitry, there are two coupling methods; one is capacitor coupling and the other is transformer coupling. Capacitor coupling is the traditional, low cost method. It is somewhat stable but transfers only voltage, not wattage (i.e., not real energy). With transformer coupling, about 90% of real wattage is transferred (there is still a transformer loss of about10% of wattage – voltage is not affected). Constant and low output impedance – One of the benefits of transformer coupling is that it facilitates constant low output impedance. Low output impedance is critical to the design of a good preamplifier. No negative feedback design Advanced tube technology voltage regulation – For quieter and more dynamic operation, the L-5000 DHT has an ultra-high speed automatic voltage regulation circuit, utilizing vacuum tubes. New vacuum tube damping technology – Allnic Audio’s patented "Absorb GEL tube damper" technology prevents harmful vibrations from reaching the signal / gain tubes and, therefore, prevents micro-phonic noise propagation in the tubes. Provided other tube components do not introduce micro-phonic noise into your system, with the Absorb Gel damping system, you will enjoy a degree of transparent sound that will surprise and please you. Precision attenuator volume control – The L-5000 DHT does not employ a digital IC volume control or a low-cost carbon film volume control with a motor. Allnic Audio has developed a precision oil clutched motorized attenuator; the L-5000 DHT has no (± 0db) channel unbalance at any volume level. IMG_7525 2.heic.pdf
  2. Great vintage preamp. Class A with excellent adjustable phono stage. In great condition. Bought as part of the set but using my home cinema as pre due to room issues and eq. Comes with 110/220V selectable source. Quite old but very good condition. Want £275 + delivery. Post anywhere for cost - guess around £15 uk, £25 EU £40 elsewhere but ask so I can check.
  3. With the Reviews section in abeyance I thought I would still go ahead and give you my thoughts on the little Khozmo passive preamplifier: It was twenty years ago that Sgt Pepper taught the band to play…… Well it was actually 34 years ago (yes 34 years!!) that CD hit the (audio) world. It brought a whole range of plusses and minuses that have been worked on for the last 34 years. Real progress has been made. It took some time but it has become the mainstay of music delivery even though now it is being overtaken by streaming. One of the possible plusses involves the audio bit of the DAC. Nearly all DACs use opamps or discrete components that provide an output of 2V. This has become an unofficial standard, although the XLR variant gives 4V. With power amplifiers requiring about 1V for full output this allows a change in the role of the preamplifier. If the output of CD/DACs was 2V and the power amplifier required 1V then all that was needed was to attenuate the output signal down to 1V or less. This brought about the possibility of using very simple single/two component (preamplifier with no amplification) attenuators. The birth of the passive preamplifier/attenuator. Making the thing less hair shirt some added source switching and heaven forbid……..remote control. Now this brought great promise. There would only be 1/2 components between the DAC and the power amp. How could it get any better? Stunning sound quality, cheap costs and every one would be smiling, bar preamp manufacturers. But it did not work out that way. Everyone and their dog built a pot in a box, one set of input and output connectors and stunning sound flowed………er not quite………or not always. For me I saw this happening and bought a CD player with the volume control built into the CD player itself. It had a digital volume controller. How could anything go wrong? It did and I preferred my active preamplifier. In fact, the in-built volume controller sounded terrible. Why? Well despite the great promise, the volume controller worked by ‘decimating’ the signal. It reduced the volume by chopping off some bits. Awful. They have got better now. OK along comes Creek who actually put together what I regard as a cracking item, the OBH 22 preamplifier. It has three inputs and two outputs. A source selector, a volume control and used a high quality Blue Alps pot, all with a natty remote control. With my ARC valves it required a really brilliant preamp to sound better. All it would do that was negative was to lose some bass impact and soften the overall dynamics. But it was incredibly natural, ultra-detailed and very easy to listen to even on rock music. However, occasionally it just did not work with some equipment and it sounded soft and quite mushy. Not often but it required care in matching impedances. Using long interconnects between the attenuator and the power amp could lead to problems. But taking care to keep interconnects short (1m) then all was OK. However, it is no more as Creek do not make them anymore. A pity. Recently there has been a huge interest in passive attenuators and that has produced many variations on a theme. There are many simple pots in a box. There are more sophisticated step attenuators where individual resistors are soldered onto the volume controllers and instead of the volume being continuously variable it is attenuated in steps. There are variations of even this type including shunt attenuators where one resistor is always in circuit and another is used to provide the steps of the volume control. There are Light Dependent Resistors where a change in the voltage of a small light source affects the LDR, it changes its resistance and it is connected to the output volume. And of course there are transformers that attenuate the signal either through Transformer Volume Controllers (TVC) or auto-formers. As you may expect all have their advocates. I am looking at the Khozmo Passive Preamplifier (Attenuator), which is a stepped shunt attenuator. This is a company I have not come across before. They are based in Poland and you buy direct from them via the internet. This is something that is becoming more common and promises to give good products at a reasonable price as the mark-ups from the distributer/shop are not added into the price. However, you have to buy blind and rely on any money back promises and reviews like this one and people’s experiences. It is possible to buy this shunt attenuator with different quality resistors for both the shunt resistor and the switched-in resistors. Khozmo sells the standard attenuator with Caddock and Vishay resistors with upgrades possible to the Takman Rex and Vishay Z foil resistors. They are sold with either 10/20/50/100/200Kohm input impedance and in my case the 10K variant was recommended as I was using it with the Nord Class D power amplifier. The attenuator goes from -60 to 0dB in 48 steps (2dB increments from 1-11 and 1dB from 12-48) with make-before-break switches, hard-gold contacts, ±0.1dB channel matching, just two resistors in the signal path at any given setting, CNC-machined PA11 aluminium bodies and a precision ball-bearing support. Everything is hard wired with solid silver core wire. Because I listen slightly off centre I asked for the dual mono version which is slightly less convenient than using a stereo version but you do get control over the balance. My attenuator had three input and two output with phono connections (which led to an odd problem later). The box is very well made. It is quite weighty and looks the part with wooden cheeks and the controls have a nice solid feel. Overall, including the attenuators, it is well-built and it is hand made to boot. If you buy the stereo version, it can be remotely controlled at extra cost. The really good news is the basic model costs $300. My model cost $400 which with postage made a landed priced of £320. So how did it sound? Well I wanted to use it with my Auralic/Aries+Audionote DAC2.1x front end, the Nord Class D power amp and Audionote E/HE speakers. I therefore had an issue with the power amp needing XLRs and the Khozmo I bought using phonos. Maybe I should have got the XLR variant. Anyway in goes two amorphous make XLR/Phono adaptors and I get a sound out that it is very good. But I can surely do better with a Cardas XLR adaptor? I buy a pair and things did not work out. So eventually I go for the Neutrik XLR/phono adaptor and all is now well. Well enough prevarication how did it damn well sound? Well as you may expect from having just a couple of resistors in the circuit extremely neutral and natural. The 3D soundstage is big and it has great width and depth and dare I say it height. It also shows up a lot of studio recordings as being very dry and artificial with their limited soundstages. I used the old demo favourite of Misa Criolla featuring Mercedes Sosa and you can hear the large acoustic it was recorded in and the echo fading away. As you may expect there is no noise coming from the speakers with a passive attenuator and an extremely low noise power amplifier. You can therefore easily hear the echo from the acoustic as it gently fades down to zero with no cut-off. The bass was big and powerful with no overhang. The bass tonality was very good. It was possible to easily hear the different types of bass and the tricks done in studios. Onto something musically different, Dystopian Overture from the new Dream Theater album in 24/96. The tricks used in this studio creation were easy to hear and very clear. In the middle of this track there is ‘kitchen sink’ moment where all sort of instruments are added and taken out of the mix. Their different added echo and layering is easy to hear. After listening to that section of music it feels like you have been on an audio assault course. You have been overwhelmed and given a feeling of being taken over which may have been what the band wanted to paint for this desolate future. Other preamps can become confused by this passage making it messy and less unnerving. Of course it is not perfect. Despite using high quality resistors the dynamics are not as sharp as those from active preamps and the high frequencies do not have the air of transformers or active preamps. Active preamps still have that huge drive and attack and this resistor based attenuator is a little softer. But for me it is more relaxed and easier to hear for longer periods of time. Maybe not as showy. If you are concerned about whether everything will work and need to check the impedances Arek is great with advice and always responded to my e-mails very quickly and allows return of the product if it does not work out for you, within a reasonable time period. In conclusion given that some of the other preamplifiers I used (Nuforce P9 active preamplifier, Audionote M6, Creek OBH 22) were far more expensive than the little Khozmo and it was not embarrassed or shown to be deficient apart from a few minor areas makes it a bit of a bargain. It is highly recommended and you can get any variant you want. So let me introduce to you The one and only……….Khozmo…..

  5. Pro-ject Pre Box RS in silver, balanced valve output stage, remote control. (nb. the RCA outputs are fixed, it should come with XLR-RCA cables but the previous owner did not include them, I will throw in custom made by Mark Grant 50cm Van Damme Green 110 Ohm Neutrik XLR to Neutrik Profi-phono RCA if your power amp has RCA inputs). Pro-ject Power Box RS Uni 4-way in black, linear power supply that can feed 4 Pro-ject RS components. The previous owner also did not include the basic SMPS for the preamp, so these units need to be sold/bought together. Both in excellent condition. £550 delivered in the UK. Images won't appear for some reason, here are links: http://imgur.com/a/0kDNG http://imgur.com/a/hXF9G
  6. Naim Nac 122x pre amp. £375. Full working order and stunning condition with original box/packing/manual and of course remote control which is hardly used. Cosmetically almost perfect, the only blemish is a tiny scratch near the volume control as shown in pics, which I only noticed when taking pictures for this ad! Collection from Brighton or can send at buyers cost.
