Well said, Bombaywalla. In audio as in many other technically complex fields, "it depends" or "maybe" is often the correct answer. We all hunger for yes and no answers but there is reason why "the devil is in the details" is a well-worn phrase. I know nothing about output ripple (although I'm pretty sure it's bad). What I do know is that several of the designers of products I admire devote a lot of attention to power supply design and execution. In my technically ignorant opinion, it's one of the reasons why the idea of buying an amplifier based on weight, as crazy as it sounds, is not such a bad idea. Good transformers and power supplies are usually pretty heavy, so all other things being equal (not comparing Class D to Class A, and normalizing for the weight associated with "machined form a solid billet of unobtanium"), there is a positive correlation between amp weight and SQ. IMO.

Drewan77- From your posts above it looks like might have some advice for me as I consider taking this route to upgrading the SQ of my system which can read about here. I am considering actively crossing over the output from the pre-amp so as not to run the field coils on the OB full range. Since my gear is in the LR, I do not have any realistic options for room treatment. I would like to insert the DEQX in the processor loop of my Doshi pre-amp because first, I love its sound, second, I use two sources, and third, I may want to use its DAC someday when my Transporter goes legs up, networked to my server. I am not a very technically oriented guy, so please keep that in mind. Also, if you think we should take this off-line, just send me a pm and I'll get back to you. One concern I do have is that the newer DEQX products seem to be very much oriented to an all-in-one PRE/DAC/EQ use and I'm not sure if that makes sense in my situation. Luckily, I have the ability to (relatively) easily move my speakers out onto a large screen porch to get speaker response measurements. |
