  1. For me, it got of to a bad start. There is a tendency now to have click-bait articles with headlines that are just nonsense. They polarise views, you are either for digital or hate it. When real life is more complex, which is what he argues later on with respect to timing. I hate this 'us or against us' type of argument whne life is more complex. He talks about Nyquist sampling and then provides no evidence to question it apart from 'musicians don't like digital'. The reality is the reverse as most musicians do not hate digital, apart from a few musicians like Neil Young. He also provides no evidence for questioning Nyquist. He adds some discussion on timing but it is loose and a bit waffly. Where are the peer reviewed papers that prove humans are incredibly sensitive to timing data and how that impacts audio? I know this is a light article but he could say there is work being done and quote the papers, if there are any. There are some papers looking at how humans perceive sound. The 1950s frequency response, THD and noise have run their course as most equipment meets those needs. Are there other 'distortions' that impact sound quality? What are they and how can we make audio equipment deal with them? For me digital failed initially because manufacturers argued digital is perfection based on science and then made products that weren't. It has taken years to make equipment that performs as the theory says it should. It was this not so good engineering that caused real problems. This has got better but is there something else? People like Rob Watts are questioning these assumptions and a few people are looking at what impacts how people hear audio. That for me is the best area to look at and not questioning Nyquist sampling.
  2. Tis true.....And they have a knack of taking a reasonable song, jazzifying it and make it utterly boring with a dynamic range of 4 db....doobie, doo.... But PF Dark Side of the Moon on SACD played through an Esoteric P03/D03 does sound rather nice. Ba, doob, it,ra, ra.... I am afraid Keith has er...gone.....left behind a pile of ashes......
  3. You should be aware that Sajid Javid, Home Secretary said: As Home Secretary, I’m doing everything in my power to tackle this scourge. Our new Offensive Weapons Act is a central part of this. These new laws will give police extra powers to seize dangerous weapons and ensure they are less likely to make their way onto the streets in the first place. The Act will also see the introduction of Orders – a power the police called for. YOU have been warned....
  4. What a boring lot. I thought it would be Linn vs Naim, an infamous company: If you sell that lot you can kiss goodbye to selling our stuff, who pays salesmen the most commission, the most unreliable product positively reviewed (including explosions), company well reviewed selling an electrically dangerous product......etc....... Or maybe not.
  5. Getting a good measurement is fairly straightforward but there are a few mantraps. If you get reproducible results that look/compare the same then that can be a good sign. Measure at ear height and if you can it will be worth measuring at a few seated positions and average the results. I use the XY equipment and that provides a detailed low frequency sweep to show bass response. It highlights peaks and troughs and will provide a filter that 'counteracts' problems. I would try to do a sweep and then see what is happening at the bass end. It may then be worthwhile moving the speakers and see what happens to the peaks and troughs. Aim to minimise them but getting them totally flat may not be possible due to the room. And when it looks better try listening. What helps is to look at the peaks and troughs and use a calculator that relate the peak/trough frequency to wavelength. That will tell you whether the problem is in the long axis of the room, short axis or an issue with the ceiling. Once you have done that you will have solved a lot of problems etc. Try not to get too infatuated by them as you could end up chasing your tail. Then look at mid-range, RT60 times, waterfalls, etc. Personally I would not advise any DSP/filtering....you have taken the bother to get a great system and this would digitise the signal and may cure one problem and create another. Try it in software and hear what happens.
  6. It has all been done before by many universities and audio companies. If you measure a whole range of SS amplifiers/cables/DACs you find there are differences but they are very small. If you then get a group of people and see if they can detect those differences such as very low levels of THD you find there is no way they can tell those difference when using simple sine waves. If you do double blind tests in a lab then again no one can tell the difference between all those items. So you conclude what? Given those test condistions you can't tell any difference between all SS amps that meausre 'well'. However, when you use the SS amps at home under normal listening conditions it is easy to hear differences between say a Naim, a Quad and a Mola Mola. Yes it is easy to take account of volume levels but blind listening tests can be artificial and you feel you are being tested not the component. So are we measuring the wrong thing? Probably, but what is the alternative? Far more complex signals like music? Better double blind listening tests? If it was easy as meauring differences with home software and microphones it would have been done decades ago. Companies like Nordost/Naim have access some of the most sophisticated measuring equipment in the world and they have not been able to simply say look here are the differences and they can be heard/sensed by people. So Naim have introduced their new DR amplifiers which reduce the noise levels of their amps but they are already very low and using double blind tests we can't hear the differences. But the DR amp sounds better in a home environment. In an academic sense people are looking at using multiple sine waves of different levels with a structure that resembles music. If you remove the very high frequency harmonics from a signal can people hear it even if they are at 25kHz? There is a recent paper saying yes. A complex subject but there are companies who do NOT want to explore this. The community has built up a framework established in 50s and 60s that say THD, noise and frequency response are the key measurements. Companies have chased these numbers for 50-60 years. But little has been done on what we percieve as important. THD is easy to measure and my amp has 0.05% which is better than yours at 0.06%. Great marketing and you see it all the time. So what, most SS ,mps meet the minimum requirments maybe there is something more important to measure such as phase or IMD or.....???? I am not against measurements. companies use them to design new items and ensure the QA. But the better ones will then listen and tune and repeat the measurments. The less good just churn out a product, say the measurments are good and close the door. And when people say it doesn't sound good they immediately quote all the measurments (THD, noise and frequency response) and say you are imaging it or are deaf. Normally they go out of business as people do not want to buy things that measure well but sound poor. Diesn't stop the next new company from doing it though.
  7. Tim, Now come on man, where is your peer approved testing protocol that takes account of every variable including: a) measuring every known electrical parameter of every cable b) triple blind testing procedure c) full statiscal analysis to deal with all biases including personal equations (only fully tested and approved people to be used) d) superb audio equipment which has been fully characterised and measure superbly (Sound quality is irrelevant) e) temperature and humidity controlled environment f) no music, only white noise and possibly pink noise with full frequency sweeps at all audio levels from 70db up to 0db. g) full set of blindfolds h) no talking or any actions including tapping of feet or head movements i) most importantly clean white lab coats and clean clipboards j) NO MUSIC and do NOT enjoy it. On no account are people to listen in a relaxed environment, to music they enjoy, as the point of an audio system is to pass measurment tests and not enjoyed. If you do find differences they will NOT be accepted unless you can personally supply a full technical explanation of how it works. OR carry on Tim, there are some who will not be convinced, such is life. Use the system to play music and as always Enjoy the Music.
  8. He only used his ears to listen, I think. Not sure there is any other way to listen. Through the nose???

    Just checked we get 53,657 different vistors a month and the same number of visits per month as PFM (250K) and that makes us one of the, if not the biggest, audio forum in the UK, excluding those where TVs are discussed. Keep going chaps, we want more....well better as well.....
  12. I have heard Tim's system and it is not only high resolution but very musical and organic. Must be even better with the V140s. I would give it a bit more time to get a broader view of how the cables respond and for any settling of the cables (if such a thing exists). Silver cables with less treble that will surprise a few but it happens with high quality silver. Hollow cables have been used before and some originate from microwave cables. As I have only heard a DAC microwave cable can't really comment. Of course, the worst outcome will be a preference for the treble of the Black star and the bass of the Cryo Ref. The Oyaide may be a bridge between the two.
