^ Interesting observation morphsci, as a past owner of a PinkFloyd modded V3 and owner of an also PinkFloyd modded V2 I can not agree with you. But that is OK, we all hear differently.
DefectiveAudioComponent, IMO the bass is one of the best attributes of the X-Can V2 and V3. Granted my impression are w/ modded units using the Little Pinkie PSU. BTW, I found the Solo SRGII w/ PSU1 a better match with the HE5 than the EF5. Good luck.
