Should I sell my accuphase for this schiit

@georgehifi I haven't done much digging to verify how significantly the quality degrades when bridging an amplifier.  Though I did recently look at the "Guaranteed" specs of the Accuphase A-65, for example, which is a super high quality amp with a massive power supply.  It shows an improvement in THD while in bridged mode, provided speaker ohm is not less than 4 ohm.  However, they still claim bi-amping is best for "optimum sound quality".

Stats below from  http://www.accuphase.com/cat/a-65_e.pdf

Total Harmonic Distortion Stereo operation (both channels driven) 0.07% with 2 ohm load 0.05% with 4 to 16 ohm load
Monophonic operation (bridged connection) 0.03%, with 4 to 16 ohm load

Can anyone explain the above stat and why it contradicts the claim that bridging has a  negative affect on distortion?

All you have to do is look at the impedance loading recommend after bridging compared to when in stereo and that will give you an idea all is not well when bridged. Everything takes a hit, except for 8ohm wattage output.

Well, I'm not sure you looked at the specs... The distortion is clearly lower down to 4 ohms.  Can you explain that?

This by them says it all.

Better off with a 20w Class-A Aegir in stereo feeding both tweeters (that will stay Class-A much longer where it counts in the highs, than a mono one doing full range), and then a 100w Class-A/B Vidar feeding the bass.

I won't disparage Schiit gear as I own two pieces and couldn't be more pleased.  However, I was expecting somewhat of a retraction, being that I put up solid evidence that bridging isn't as bad as you claimed... at least with top quality gear.

Another factor here is If the poster takes your advice, you should make him aware that there is no attenuation controls on either amplifier so, he will likely have a significant imbalance between lows and highs that will make his Schiit sound like s***.
