  1. BRYSTON 8B ST 4 CHANNEL POWER AMPLIFIER On Ebay https://www.ebay.co.uk/itm/BRYSTON-8B-ST-4-CHANNEL-POWER-AMPLIFIER-GREAT-CONDITION-WARRANTY-TO-MAR-2020/113382330637?
  2. Nord One Up SE NC500DM Mk II By Alex Colburn A little over two and a half years ago Colin North of Nord Acoustics launched the Nord One Up NC500DM dual mono stereo power amplifier and One Up NC500MB monoblock version. Nord’s NC500 family of amplifiers are based on the Hypex Ncore class D technology and capable of delivering 400W into an 8 Ohm load. One of the keys to the amplifier’s excellent performance was the Nord designed input buffer incorporating Sparkos discrete regulators on the power supply and a variety of user selected dual discrete class A op amps from Sonic Imagery, Sparkos or Burson rather than the Hypex designed monolithic amplifier. Discrete op amps are used extensively in professional audio due to their superior performance in terms of sound quality, noise and output current. On the face of it, using a class A amplifier to drive a class D output stage seems counterintuitive but the combination works very well. At the time of its launch, George 47 did an excellent review of the original amplifier that is available here: https://www.hifiwigwam.com/nord-one-up-500-dm-st-dual-mono-stereo-amplifier-review/ More recently, Colin has launched a new family of One Up NC500 amplifiers under the Mk II guise. The new range features a completely re-designed buffer board designated Rev. D. You don’t need to buy a new amplifier the get the latest spec, all older amplifiers can be upgraded either as a DIY installation or a return to base if required. The new board moves away from the original dual op amp design and utilises a pair of single discrete op amps based on a design originally developed back in the 80’s by Deane Jensen of Jensen Transformers for professional audio use and utilising a much larger pin footprint than the standard dual-in-line devices. Moving away from the dual op amp topology has some technical benefits, cross-talk inherent to the dual devices is eliminated and the single devices have considerably higher class A output drive capability. The heat sinking of the Sparkos discrete regulators has been beefed up to cope with the increased current demand. In addition to the use of audio grade polystyrene capacitors throughout, the new topology has allowed fine-tuning of the supporting circuitry and improved noise and RFI counter measures. Nord offer two op amp options for the Rev. D board, the Sparkos SS2590 which is a naked PCB device and the Sonic Imagery 990ENH which is fully encapsulated. Differences between op amp options on the Rev. D board are apparently less than found with the Rev. C board offerings according to Colin but some may prefer one over the other. As a fan of the Sonic Imagery 994ENH op amp in my Rev. C boards, I opted for the Sonic Imagery 990ENH in my Rev. D boards. Nord Rev D buffer board In light of the excellent performance of the original Mk I amplifier with Rev. C buffer, my expectations for the Mk II were relatively modest but I ended up being proved completely wrong on that point! Before undertaking any critical listening, I allowed the amplifier to run up to a stable operating temperature over a little more than an hour. Starting the audition with my usual collection of well-loved favorites, it quickly became apparent that the Mk II amplifier was giving me a significantly more expansive and precise soundstage. Both artists and instruments are presented in a rock solid 3-dimensional image. I’ve used the optical analogy because it’s like viewing a larger, sharper image. The audition continued largely playing tracks I knew imaged well as I wanted to explore how good it could get. After many tracks, I was convinced the Nord Mk II was getting the very best from any spatial and ambience content in a recording in as much as the Glastonbury Tor speakers were capable of reproducing. Moving on, the Mk II retains all the great qualities of the original and adds to that an improvement in dynamics. Faster edges to bass notes add texture, authority and weight to the bass, notes start and stop as they are supposed to. I find a good measure of a system upgrade is when it spurs you on to playing music you previously shied away from and the Nord Mk II certainly did that for me. The net result is to move the recorded performance that bit closer to the live experience. Class D has come of age and is here to stay, all be it with the assistance of some class A magic from Nord! If you are a Nord One owner with the Rev. C buffer boards I can only recommend you upgrade to the Rev. D boards, it’s well worth the cost IMHO. Upgrade prices start from: £658.80 including VAT for a stereo pair.

    SALE Pass Labs XA60.5 monoblocs

    Pass Labs XA60.5 monobloc power amps. Super high end and ridiculously expensive amps from this top US brand. Bought from another wammer and hardly used before I emigrated, much to my dismay. Pure class A. They produce such musical detail it's astounding with oodles of quality power. They are RARE to find for sale in the UK and were imported from USA by previous owner...therefore they are 140v and come with a step-up transformer. Boxed as new. 4500 GBP. They provide 60w per channel into 8 ohms, 120w into 4 ohms. Full power gain is 1.10, high freq 100 khz, gain is 26dbs, power consumption is 200w, distortion is just 1% at full power. They measure 19x7x19 inches and weigh 62 lbs. Courier options given on request, all located in Wells, Somerset. I won't be back to give any demos until beginning of April, but collection is welcome before then. Would obviously prefer to keep them in the Wam so giving it a little while here before I advertise them more widely. Happy to listen to sensible offers too.
  5. Hello wammers, In order to keep my furniture as it is I am looking for a power amp that is physically small but near to or high end. The T + A Amp 8 fits the bill size wise but does anyone have an experience of this? Or of any alternatives? Ideally not much bigger the the Amp 8 - 10 inches by 10 inches approx. It will be driving Spendor S5E speakers (87db sensitivity). Can be new or used but not much more than £2k if possible. I welcome all ideas! Richard A

  7. Hello. I`m not sure anyone here can advise us,but we have just bought a brand new Quad Elite power amp and have rigged it up to our Quad 34 pre amp (going strong since late 80`s) The Elite is replacing a Quad 306 which we decided to put into retirement! Anyway,after setting it all up we noticed a drop in volume. A comfortable volume level using the 34/306 was at roughly 12 o`clock on the volume control...to achieve that level now with the 34/Elite, the dial is at 2 or 3 o`clock. We read a couple of reviews where people had put the same pre/power amps together and they were pleased with the results and volume didn`t seem an issue.Hence this question. Thanks for reading and hopefully giving your thoughts on the matter
  8. Confirmed as sold. Thanks to everyone for views and comments. Hi, I'm selling my Gamut D200mk3 power amp which is in immaculate condition and complete with manual and original double box. Bought from Rochester Hifi as demo in 2007 and has provided fantastic service since then. Looking for £2,200 cash on collection or if buyer wants it shipped it will be £2,300 via PayPal with buyer paying for shipping. Some links to reviews below, all consistent in their high praise of this amp, great slam, control but, above all, musicality. I've loved having this amp but I've decided it's time for a change and make my final splash on a Karan amp - I'll probably regret it up that's what this hobby does to you... http://www.dagogo.com/gamut-d3-preamplifier-d200-mk-iii-amplifier-review http://www.hifiaudiosound.co.uk/amplifier_gamut_d200_mkiii.htm http://stereotimes.com/amp082407.shtml Any questions let me know. Many thanks, Mike.

  10. Hifi Pig have reviewed the Trafomatic Belus Hybrid. http://hifipig.com/trafomatic-belus-poweramp/ ''Trafomatic is a realatively recent addition to the high-end hifi fraternity and perhaps best known for the £100,000 Elysium monoblocs. This is a Serbian company that exudes quality, detail and perfection. The Belus power amplifier up for review here might not be as expensive as the Elysium, but at a more attainable £3250 this is no less a product says Janine Elliot.'' http://www.bd-audio.co.uk/product/trafomatic-belus-hybrid-power-amplifier/

  12. NuForce's superb STA200 class a/b power amplifier seduces David Vivian in this months Hifi Choice Magazine and gains a Recommend award. David Vivian observed:- "First impressions with the Edwards SP2 in situ are of clarity, exuberance and power that suggest the small amp has the compass to deal with the whole gamut of genres. There’s warmth and colour and tactility to the sound possibly leaning towards a slightly hyped presence, but it’s thoroughly engaging all the same." "Snappy timing and a taut, agile bass performance quickly stand out with the gloriously laid-back sax and keyboard-led fusion of Get Up from Jeff Lorber’s latest album Step It Up – his most enjoyable work in years, despite the predictably formulaic structure and arrangements. There isn’t quite the air and openness I’m used to with the P1, but images are tightly focused and extend convincingly beyond the confines of the SP2’s cabinets, giving a fine sense of breadth and depth." "Good, too, is the way detail sounds true and natural and meshes unobtrusively into the larger sonic picture. Ambience is nicely conveyed and supplies the requisite atmospheric backdrop to Kate Bush at her most ethereal during the An Endless Sky Of Honey half of Aerial. Biffy Clyro at their most raucous is a little less successful." "The NuForce amp doesn’t smudge edges or blur textures, presenting performers and their acoustic environment as a coherent whole with the full spectrum of tonal colours and beautifully resolved instrumental timbres." "And as long as you don’t over stretch its speaker-driving capabilities, it will have no trouble filling a large room with high-quality sounds." Summing up David Wrote:- "It may be small and plain, but beneath that nondescript wrapper, the STA200 is a power amp of some distinction with solid musical instincts and a slightly rose-tinted presentation that, nevertheless, consistently rewards and is easy to live with. In a downscaled audio world, here’s an upgrade well worth auditioning" We Like:-Build and finish; compact size; beguiling sound quality Overall:-Teamed with a talented source and dac/pre-amp, this is desktop hi-fi at its best. 4.5 Stars Cost £899 NuForce STA200 Product Information Contact Information

  14. VAC Auricle Musicbloc Valve monoblock amplifiers. Fully serviced, and boxed, in superb condition. £1550 plus postage or collected from SE London.Wonderful sounding 70W per channel valve monos designed to get the clarity of 300B amps with the power and authority of KT88s. These can use KT88, KT90, or KT120. And they really look fantastic.The great thing about these amps are that they are powerful enough to use with insensitive speakers (I've used them with 86dB Harbeths) but they are so subtle and quiet they work superbly with very sensitive speakers. The clarity is exceptional, and whilst they have better resolution and clarity than any amp I've had before (valve or solid state), they have all the magic with voices and instrumental tone that we look for in valve designs. I've also used them with Vaughan Cabernet 1, which is very much a full range speaker, and they had gripping live dynamics. This review is a nice summary.http://www.positive-feedback.com/Iss...ac_auricle.htmThe current VAC amps are extremely expensive, so these are an ideal way of tasting the magic of Kevin Hayes' designs at a relatively affordable price. I will supply them with 4 x Philips ECC82 input valves and a virtually new matched quad of KT120s. Input Impedance is 100Kohms, which gives most preamps an easy ride, but they are not very sensitive so do like a reasonable amount of gain from the pre-amp. I used them with an Audio Research LS26, which was a very good match. I also briefly heard them with a Shindo Aurieges, which sounded great; a very seductive pairing. Biasing is done manually by the easily accesible dials on the front panel. They have taps for 2, 4, and 8 Ohms, which makes them extremely flexible.They are reassuringly weighty, due to very substantial output transformers, but they don't get hot (except for the valves) and they run quiet.The service was done by the peerless Graeme at Ampregen, who made some subtle improvements, such as extra damping to make them even more quiet.Finally, VAC are one of the most helpful companies I've come across; the designer, Kevin Hayes, is very patient with any questions and an all round good guy of the industry.http://i1204.photobucket.com/albums/...m/IMG_8199.jpghttp://i1204.photobucket.com/albums/...m/IMG_8197.jpg
