I actually think that it is coming from Nicki, her chair and perhaps her bow. There is a lot of it going on. And that is just with my humble LPS 1.2, Ultra Rendu, Chord M-Scaler Chord Hugo TT2, KGSSHV Carbon into Stax 007 MK2. Can you imagine what I would hear with an Optical rendu. jaaptina 1 Link to comment

lumos Posted May 28, 2019 Share Posted May 28, 2019 I agree, although it astounds me how many recording studios have really creaky chairs. Link to comment
lumos Posted May 28, 2019 Share Posted May 28, 2019 That is precisely why I am hesitating to order an oRendu, in the last 24 months I have bought 3 Sonicorbiters, 2 MicroRendus, 3 UltraRendus and yet I still find myself adding the oRendu to my basket. I really had hoped you had gone from ultra to optical in your system then that would have been a good data point. Of course I should wait and go straight to the Ludicrous Rendu but as Oscar Wilde said the only way to get rid of temptation is to yield to it. daverich4 1 Link to comment
Popular Post lumos Posted May 29, 2019 Popular Post Share Posted May 29, 2019 I suspect that a large proportion of oRendu customers will already have an Uptone supply powering something else. My view would be to try ones Uptone LPS with ones own oRendu and if it works use it and if necessary purchase a second to backfill where you took it from. If it doesn't work then buy a different supply. I love the performance, form factor and customer support from Uptone and I have never really thought about going elsewhere.

As edges from the input stream go into a circuit each and every one of those edges creates a current pulse on the power and ground network inside the chip and on the board. The timing of that pulse is exactly related to the timing of the input data. The timing of the input data is directly related to the jitter on the clock producing the stream. This noise on the PG network changes the threshold voltage of anything receiving data inside the chip, especially the local clock going into the chip. This means the phase noise spectrum of the data coming in gets overlayed on top of the phase noise spectrum of the local clock. It's attenuated from what it is in the source box, but it is definitely still there. Dear John, I am in awe of your patience. I used to believe that everything in the digital domain was the same until I saw that data in an oscilloscope and realised that, in fact, nothing in the digital domain is really digital at all. States do not change instantly from a 0 to a 1, there is a leading edge slope and a trailing edge slope. You now have the problem of deciding at what voltage will you say the state has actually changed. Is everything in the chain doing it the same, or even consistently. As Rob Watts at Chord demonstrates, the human brain is incredibly sensitive to timing errors and its impact on the sense of realism. But none of this really matters. I don't really have a good sense of hearing and I always go to the bother of double blind testing new equipment. I start off being cynical and sometimes I am proved wrong (my microrendus were better than my Sonicorbiters and my Ultrarendus are better than my microrendus. The Uptone Audio power supplies made a positive impact. When the DAC test revealed that I had preferred the Chord Mojo to my Naim DAC in nine out of 10 tracks I sold my Naim DAC. I have never been able to discern a difference with interconnects, power cables, speaker cables. So for me John has earned some trust in an industry where very few do. This is not homeopathy, here John explains a real mechanism of action and the price of the equipment feels very much like cost plus as opposed to the usual "how much can we charge whilst keeping a straight face" strategy. The only data point the matters is do we like what it sounds like. If I love the sound then nothing really matters. And the optical rendu plus module will not even buy you a power lead with a wooden ring on it. bunno77 and Albrecht 1 1 Link to comment
