As the title says, I have both reveivers right now.
Correction: "The v2 I've had for a month, the v1 is a few hours old." - was initially written the other way around lol
I've just started running it in for (a probably excessive) 72 hours. A Billy Idol album is being fed to the optical in from foobar2000 on my PC. The receiver is driving a bunch of resistors configured into 6 ohms which are able to dissipate about 30 watts. They're getting about 80v peak to peak which is about 15 watts. A sine wave 80v peak to peak into 6 ohms is a lot more than 15 watts, but almost no music except maybe dubstep comes close to the power of even half a sine wave.
Anyway, once v1 is run in (to my and most everyone else's satisfaction), I'll be comparing it's sound to the v2 in this thread. I'll be using a pair of 2019 ATC SCM20 Pro PSL Mk2 speakers. They are different than the 20-30 year old Mk1 pair reviewed here. These have a new in house made tweeter, a revised midbass, and a lower crossover point. They're very revealing speakers, the tweeter is ATC's new "s-spec" model, used in their range topping speakers which cost more than most new cars. The magnetic gap is fully saturated, pretty much eliminating harmonic distortion. It has a dual suspension ensuring pistonic motion - it's great. The midbass uses their Super Linear motor and has extremely low 2nd and 3rd harmonic distortion, 10-15db less than most high end speakers. They're not large speakers, so the bass is never overwhelming, but it's accurate and I'm used to their sound so can judge the bass properly (I've had them over a year now). I'm bringing up my source and the other associated equipment now so it doesn't need to be a distraction later.
Also, I have a Siglent SDS 1202X-E and an RME Babyface Pro (non-fs) interface. I'm not an expert and have never done measurements of audio equipment myself, but if someone knows how I might be able to use these to compare the receivers while I have both of them, I can follow directions. We could exchange PMs and post results into this thread. If my equipment isn't good enough it wouldn't surprise me - I use the scope for power supplies and small signal work
