  1. According to Tim, there are no capacitors in the signal path in the May.
  2. Look at the amplifiers gain and sensitivity, mine are about 26db gain (anything above 25 db should be fine) and about .8 volts for sensitivity (.8 volts input equals full power output) and that should work fine with Holo May. I use HQplayer as my up sampling software AND volume control. Although with some older recordings when I up sample to DSD, I am cutting it close and sometimes run out of volume. DSD reduces output by 6 dB compared to PCM (1/2 less output voltage), plus in HQP I set max volume to -4 dB to avoid digital clipping. Hence on older less loud recordings I can run out of volum

    I got lucky and got my hands on a RTX3060 so I am selling this card to anyone who may want to try cuda offload with HQplayer with older CPU's to get access to additional HQP filters. I just went through and cleaned the fan blades, and cooling fins (brush and leaf blower, they were pretty clean to begin with), I also cleaned all old heat sink compound and applied brand new Gelid GC-Extreme thermal compound, my new favorite compound. I ran this with an AMD 1800x and was able to do a lot of HQP filters at DSD512, of course Sinc L, full XTR I was unable to do. With base rates below 88.2 Khz most filters worked. DSD256 with EC modulators were difficult with the AMD processor, I believe had I had a intel 6700 or 7700K I would have been able to do DSD256 with EC5 and possibly EC7 modulators. All high rate PCM, even 32fs were possible. Bottom line I had access to a lot more filters with this card then I would have with just the AMD CPU. The card is in excellent condition and was only used as cuda offload for HQP. I am asking $200 for this refurbished card, Shipping via USPS priority mail is $15.50 so $215.50 total if paying with paypal family and friends, add $7.25 if not paying with family and friends. I do not have the original box but the card will be packed in antistatic bag with lots of padding for protection. Guaranteed not to be DOA.

  7. I've had my holo may since March 31 and I have no PLL locking issues whatsoever, yes it is on. I use a custom built PC (built by me) and direct connect to the May via USB. Roon as my cataloging database and HQP as my roon output. Buffer set to auto in HQP. I never see any Locking issues on my display even when different base formats are sent to HQP from roon. I run HQP at native rates (same as roon sends to HQP), High PCM rates and high DSD rates. No issues. The Allo Digione must have very high jitter levels. May dac has been measured and found to be one of the very best ever measured.
  8. I also recommend cleaning the stock L2 fuse as EB mentions or upgrade to a premium fuse. I bought my L2 used and previous owner had installed a synergistic orange fuse which saved me $160.
  9. I have posted pictures of my mods go back mid to late April in this thread and you'll see them. I have attached my order summary from parts connexcion so cost was around $110. I used 10uF caps as that what was in the May, but as ExtremeBoky says you can use most any value and save a few more $. I used spare wire I had for the AC Voltage selector bypass and bypassing the on/off switch is just removing some jumpers. I highly recommend using 16ga wire for the AC mains in, 14ga wire required me to snip off a few strands so I could fit in the holes of the PCB. The KTE uses silver wire, I used
  10. I think GoldenOne made it pretty clear that the spring 3 is no May. So I am pretty confident it will not be 95% of the May. In my experience the PSU can be a huge percentage of overall sound quality and the May's separate PSU is miles beyond the Spring 3's PSU and I would expect the sound quality as well. I have done to my May L2 the mods that ExtremeBoky describes and they definitely improve the L2. Now I don't have the KTE to compare to my "modded" L2 but I would suspect it is right there in SQ or maybe even above as the On/Off switch bypass and voltage selector bypass made ni

    $225 PayPal family and friends, $231 PayPal without F&F. Free shipping Selling my Iso regen with a 90 degree usbpc adapter and a 6" usb a to b cable. Item is in excellent condition and works perfectly. Selling because I purchased a Holo May dac and this does not connect to the PC with current firmware installed on my dac. Also available as an add on is my Ldover (3045 based) 7-7.5 Vdc input to 5 Vdc output very low noise PSU regulator. You need to supply 7 or 7.5 Vdc in and this will output 5Vdc very very low noise (.8 uV per specs) these are 1A LT3045 boards stepping down from 7-7.5Vdc input to 5Vdc output. Perfect for a iso regen whose dac does not need the USB power. I used it with a AMB sigma 7 Vdc PSU (not included) but it would work perfect with the stock uptone supplied 7.5Vdc PSU or similar 7 Vdc wall wort. input is a 2.1mm female jack like compatible with most wall worts. Output is a 7" length of supra cat 8 wire with JSSG shielding technique and a 2.1mm male plug to fit into IR. $75 with PP F&F if bought with isoregen, $90 if bought separately

  13. Sure looks like there are voltage switches in the pictures, just like the may, The IEC would be European tho
  14. My buddy ordered his KTE on June 1 and received on June 15th. I don't know if that was a rare case or has the factory almost caught up with orders.
  15. i7-10700K with Asus Z590 Tuf Gaming plus wifi. I use air cooling in a big HTPC case and PC sits 10-12 ft away from me, noise not an issue. I don't think watt draw is to bad, I'll check HW monitor tonight for CPU package draw and UPS for total PC draw. When I checked temps Wed evening the CPU ran 54-60 C, w 1024 and my air cooler. Honestly I'd recommend a bigger GPU like 3070Ti or 3080 that would open up a lot more filters for 1024 than the 3060 does.
