Popular Post austinpop Posted September 24, 2018 Popular Post Share Posted September 24, 2018 13 hours ago, austinpop said: Yes I agree that was a very interesting and comprehensive review of Jay’s. Back when I first got the SR-4, I experimented with power cords. I found that stepping up to even a modest $50 Pangea AC-14SE MkII gave me a very noticeable SQ boost. But I haven’t gone further. Based on Jay’s review, I plan to try the experiment with a couple power cables in the $250-750 range I happen to have laying around, and will report back. I will say that even on the LPS-1.2, using a $50 Pangea on the SMPS made a small improvement for me. I’m at a point now where i “just say no” to stock power cords. I’ll start with a cheap Pangea and then make a per-component choice to spend more if the findings warrant. Works for me! Well, the stars aligned, and I was able to do this comparison tonight. Let's dive in. My chain - PSUs shown in parentheses: TLS OCXO switch (LPS-1.2) > SOtM sNH-10G switch (LPS-1.2) > Zenith SE > tX-USBultra (SR-4) > Ayre QX-5 Twenty DAC Don't ask why I have 2 switches - it's just the current state of my system! Since I varied power cables on the SR-4 powering the tX-USBultra, here is the power chain to the SR-4: Main 200A breaker panel > 6 gauge dedicated circuit > modded Hubbell outlet > P5 regenerator > <power cord under test> > SR-4 The test tracks I used was from something I'm listening on Qobuz: Bach: Brandenburg Concertos - Concerto Italiano. I tried these 3 power cables: Pangea AC-14SE MkII ($49/1m) Cardas M Power ($250/1m, bought on sale from Audio Advisor) Cardas Clear ($720/1m) First off, I will just stipulate that I had already heard a substantial improvement going from a stock power cord (something from my stock cable bin) to the Pangea. Results Each step made a difference. Pangea to M Power: this was a noticeable but modest improvement. Bass seemed a bit tighter, music had more body and heft, and a hint smoother sounding. Based on this test alone, I would have said - yup, diminishing returns kicking in. M Power to Clear: this was a startlingly large improvement! Diminishing returns would have suggested a very modest gain, but this was a whole new ball game. Music became more dimensional and solid, bass tightened even further, and took on what I have started to call the Cardas glow - which is a completely incorrect label, because it connotes that the sound was colored. Rather, it is a combination of smoothness, even creaminess, but with an actual increase in resolution and detail. I always have a hard time describing this, but I've heard it with every Cardas Clear cable I've heard. So there you have it. Power cables do matter on the SR-4. But now what? I can't possibly recommend spending more on the power cable than the PSU itself. It offends my sense of balance. I can justify to myself spending 10-20% of a component's cost on a power cable, but more than 100%! Everybody has to decide for themselves. The way I think about it is - is an SR-4 with a $700 power cable better sounding than an SR-7 DRXL with a stock power cable? I haven't done that exact comparison, but having heard the SR-7 DRXL on my tX-USBultra, I'd have to say the SR-7 rail would win. So it boils down to 2 questions: does spending on a good power cable for the SR-4 result in an SQ improvement? Absolutely. Jay's finding was spot on. Is it the best use of your $$$ compared to other optimizations? Hard to say. It depends, and only you can weight the cost/benefit. beautiful music, tapatrick, auricgoldfinger and 3 others 2 2 2 My Audio Setup Link to comment

Absolutely. Jay's finding was spot on. I currently only have one better-than-stock power cable, the Shunyata Alpha HC (high current) that I bought discounted to power my Chord DAVE nearly two years ago. The successor to that cable, the Alpha NR, would currently cost about £1,800 in the UK so would be overkill for the SR4, but I tried my Alpha with the SR4 this morning anyway. Allowing myself a little time to readjust to having a standard stock cable power my DAVE, I then swapped out the stock cable powering the SR4 for the Shunyata. Wow! The SR4 was suddenly a different beast. Everything was more solid, sure-footed and natural. From now on, for as long as this is the only good cable I have, it will be powering the SR4, not the DAVE.

Popular Post feelingears Posted September 25, 2018 Popular Post Share Posted September 25, 2018 Personally, after a few years of this “magic” with USB and power stuff, I now consider cables components unto themselves because for better or worse, I can hear them. What this means is that my “sense of balance” is no longer offset by the cost of the component attached to a cable. It is what it is and the cable companies need to put kids thru college too. And of course I have a budget so it’s not the sky’s the limit anyway. I am curious (and yes I tried theirs) about the Cardas Clear now so thanks @austinpop for putting a dent in my bank account! ? DC cables too, also components for me. Sadly I don’t find a lot (some perhaps) of consistency in one brand across components, or at least digital to analog. One brand that worked well on my DAC didn’t synergize on the analog side. And there seems to be some tuning in my system with regard to the mix of copper and silver. But that’s what keeps this hobby interesting! It’s also what has kept me from putting one brand in for everything. So far I’ve tried many but have kept Shunyata, Synergistic, Audience, Zenwave, Phasure Lush, and AV Options. Like ‘em all for one thing or another, but not interchangeably by any means as top to bottom frequencies and presentation can vary greatly. johndoe21ro and austinpop 1 1 Sum>Frankenstein: JPlay/Audirvana/iTunes, Uptone EtherRegen+LPS-1.2, Rivo Streamer+Uptone JS-2, Schiit Yggdrasil LiM+Shunyata Delta XC, Linn LP12/Hercules II/Ittok/Denon DL-103R, ModWright LS 100, Pass XA25, Tellurium Black II, Monitor Audio Silver 500 on IsoAcoustics Gaias, Shunyata Delta XC, Transparent Audio, P12 power regenerator, and positive room attributes.

Anything wrong? 18 hours ago, paulhynes said: Yes, it is about time for an update. I am behind with my estimated schedule for the outstanding custom builds for various reasons. Over the last few months the health support systems I had in place for two of my family members collapsed and I have had to make a number of trips off island to get this sorted out and to transport them for health assessments and appointments. The National Health Service is currently in a sorry state at present being undermanned and under funded. Hopefully this in now settled again for the time being although health appointments will be necessary from time to time for monitoring purposes. There have also been a number of business trips off island that took longer than usual and of course the Easter and Summer holidays. There has been a trend of re-specification for outstanding orders to allow compatibility with new developments in the computer audio sector, and a number of order cancellation transfers to deal with which all takes time to sort out and it also causes delays with the orders. The working conditions at home reached saturation point with two of us working in a rather small space stacked high with equipment, transformers, chassis, components etc. Vying for space to work had become a big issue. Also we need to create disabled facilities at home and the rooms I currently use for work will shortly no longer be available because of this. So I planned to move the business into new premises with plenty of work and office space (approx 8 times the current space), which I scheduled for takeover the first week in September. Unfortunately the move has been delayed because the owner of the premises was unable to get tradesmen in for general repairs and decorating before the move so it has been postponed until 5th November. There is a lot of stuff to move and it will take some time for an orderly preparation during the week before the move and dealing with workshop and office installation the week after. Unfortunately there will be no production work during this time. The priority will be to get the production area functional as soon as possible. My technical computer died screaming during a backup last week when the ATX power supply exploded. I was sat next to it at the time, which was pretty scary. I have replacement equipment ordered to rebuild it. I do hope the hard drives have survived, as it will be tedious and time consuming to have to re-install everything onto new hard drives. All of the above has caused considerable disruption with my work on the custom build outstanding orders with little happening over the last two months. Once we have the new premises up and running we should be able to work more efficiently than of late and my primary aim will be to get up to speed with my work schedule again. With so much happening recently I have been a little disorganised with the admin for which I apologise. This week I should be shipping out custom orders 15 and 16. Order 17 has been temporarily delayed due to a re-specification so I will start on order 18 as soon as the new workshop is functional. this is from the SR7 thread, hope it helps customer server+AudiophileOptimizer >>UltraRendu (SR4) >> Lush(JSSG360) >>> IsoRegen(SR4) >>> Lush^2 >>> blu2 >>Blaxius^2D >> Dave > HD800(SDRmod) Link to comment
