I've undervolted both my gpu and cpu and while they do draw a combined 120 watt at DSD512 with light 512+fs the whole pc is whisper quiet (gpu temperature 32 degrees cpu temperature 55 degrees). If you don't chase super 512+fs @1024 and you undervolt and watercool you can have an extremely...

Could be that the pads need some breaking in? Especially if you don't use the clamp force screws I imagine the fit of fresh pads will be different than worn pads that have shaped themselves after your head. On a pad sidenote: I improperly applied mine and now the right pads have become loose...

You ask some difficult to answer questions so you get a long slightly off-topic answer haha. I have not done a blind test but I am not sure I would pass it. I very quickly get switching fatigue and everything sounds the same. The brain quickly adapts to a given standard so I feel like the most...

Sonically it is amazing and the tone + stereo base controls make it a great and unique preamp, but I really value being able to set the preamp gain in decibels as it allows for volume consistency and level matching. I've resorted to using HQPlayer digital volume control with the HM1 preamp...

No preamp? 😲that sounds like a feature, the one annoying thing about the HM1 is it doesn't have a power-amp mode and the volume pot is always in the signal path

Maybe I should clarify since you seem to have misunderstood, before the PSM156 the HM1 had more punch and was more natural but the HPA4 had better staging and cleaner treble so while I preferred the HM1 I didn't prefer it 7k more, the gap was pretty small. Now after I feel the punch and...

So this week I received my Puritan PSM156, and while I'm confident that it made the gap between the HM1 and my HPA4 widen considerably there was also another interesting side effect. Before I had everything plugged into a generic power strip and there would be a quite audible pop when shutting...

Totally agree on gauss-short! I have a small hunch you will end up with poly-sinc-gauss-xla for classical/instrumental ;)

Just the standard one. My only grounded socket is 8 meters away so it's plugged in an extension chord anyway.. if i ever move to a house with grounded sockets everywhere I'll probably try the ultimate cable!

It arrived today and plugged everything in. It's too early to say anything about bass, energy, separation or details but there's one thing that sprung out immediately. I keep hearing about people hearing power conditioners and noticing more "relaxation" in their music, or even they felt like the...

Ok thanks for the reply! That is good to hear as I only have a single grounded socket in my house so connecting everything to the psm156 is by far the most practical solution :)

Hi all, I'm a soon to be owner of a PSM156 I figured it was worth posting a question here. I've heard the PSM156 is extremely good at eliminating mains noise but much less so at eliminating noise generated by devices connected to it. I was thus wondering if it is recommended to connect...

I posted this a while earlier but if you're chasing that NOS spring/may sound I've found the polynomial-1 and polynomial-2 filters in PCM to be a kind of 'enhanced' nos. Maybe something to try!

dac correction GPU usage went down by 8gb.. the manual mentions it affects resource consumption I just have a hard time understanding why this is a setting and not dynamically adjusted depending on your output configuration.

Definitely XLR. If you're sensitive to cable differences my recommendation is Lavricables Grand XLR which are expensive but not Audioquest levels. If you're not get some star-quad configuration copper ones with Canare or Mogami wire and Neutrik plugs. (Benchmark sells quality ones for a low price)

I don't know if I'm allowed to mention this but when I tried PGGB I simply used Qobuz-dl to rip the files from the streaming service.

This might be pure placebo but I think for the near future i'm going to stick with DSD256, ASDM7EC-super 512+fs + dac correction. If I had to describe it I would say there's a definite increase in snappiness and weight. Thanks to the measurements posted earlier in this thread it's comforting to...

Trying to enable dac correction with Poly-sinc-gauss-xla, DSD512, ASDM7EC-light 512+fs my GPU memory usage goes to 11/11 GB and CPU ram usage goes to 32/32 GB, causing my computer to slow down to the point everything starts to freeze. Switching to PCM x32 rate causes 4 GB of GPU VRAM and 1.5 GB...

The May is engineered to be usb-source immune. The USB interface is galvanically isolated from the rest of the dac and it uses asynchronous USB so it only uses the May's extremely high quality internal clock. Usb is the superior connection method as it allows you to upsample to high rate PCM and...

I believe the general consensus is that filtering also has an audible impact for hires (2x rate) content, where you'll be sure to hear absolutely nothing since any filter ringing or other effects will happen all the way up at 44.1/48 Khz. Maybe something worth giving a try?

I think the general consensus is they look like crap and ergonomics are bad but the stock cable indeed sounds very good

I'm super curious about the dac correction! Eagerly awaiting Jussi's hints on what exactly it is correcting :)

The section appears to be hastily written in response to yesterday's discussion over at the HQPlayer thread, it contains a lot of misspelled words. However the charts are interesting as it is exactly the kind of experiment I proposed. I'm very curious how PGGB achieved a very long filter with a...

The question is does it support double voltage drop sensing? Annoying thing for owners of Oor + Wandla is that the voltage sensing feature gets disabled by the splitter

Replying to myself here, anyone that was also interested in this Jussi already did almost the same exercise over on the Audiophilestyle forums, see here: https://audiophilestyle.com/forums/topic/68859-sampling-and-filtering-discussion-split-from-mqa-thread/?do=findComment&comment=1258061 (You...
