elcorso Posted April 16, 2017 Share Posted April 16, 2017 BIGGER IS BETTER !!! Please note, I'm saying bigger and not expensive ! For comparison, in the following formula: My fiancé with her lovely cavity resonance chamber: Singing in the shower she has air, presence, 3 D, depth and width. Like in real life... This is not influenced by love and not different from real live, and of course not a 'nice' welcome distortion.

Because everyone knows linear is better than switching?? Sometimes it's hard to get "switching noise" out of your whole system when you have a Class D power amp., like in some self powered Subs (my case). I don't have "switching noise" when the main speakers are feed by my Class D power amps. Maybe they have LPSU? Roch Link to comment

Harsh and etched, shallow soundstage. Disappointing. Maybe not a good DAC and speaker combo. Merrill Audio Veritas: Resolving, wide sound stage, not harsh like the Kaluga. Once again, shallow soundstage. AURALiC Merak: Inferior to the other class D products I listened to. Not as clear / resolving. Again the room might not have been the greatest. In all fairness, I will point out that 3D sounstaging was rare at AXPONA. I've heard a bunch of very wide soundstage presentations. Plenty of solid images. Depth though was uncommon. Could you list the associated gear with each of those Class D amps you listened? I stopped assisting to audio shows because I found they are more for dealers / factories relations than for customer evaluations. Thanks, Roch semente 1 Link to comment

I've heard lots of equipment in too-small rooms, set up to bowl people over with "detail," or both, which gives a hard edge to everything. Or the equipment can be set up to avoid sounding muffled with a full room, which again gives a too-bright hard edge if the room isn't full. "Everything matters" as @Barrows use to say.

And gradually improve after the 1000th hour. What brand and type of capacitors have the Crowns that needs a lengthly burn in? Roch Link to comment

Class D technology is still in it's early stage of development, while Class A (tube or transistor based) has matured. Similarly to Digital vs. Analog Audio, in the next few years Class D will become at least as good as any other amplifier technology, but more likely: Better. 60 years have passed I am still waiting for SS to reach the SQ of the Tubes ... How much more should we expect for class D to reach class AB (forget about class A) ? First commercial class D amplifier was from 1964 (Sinclair), but the first proposed was in 1958. For my taste, of course... Roch 4est 1 Link to comment

From a technical point of view they are about equal, with probably a slight edge to SS with regards to linearity/distortion. The popularity of tube amps is to a great extent due to their often simple and elegant designs, combined with their seductive sound signature (the harmonics). Provided, components of decent quality are used. Honestly, I don't care about measurements (linearity/distortion), my only need is to please my ears, not yours or those of others. The elegance of the design could be important to me, if the first thing I mentioned is accomplished. But I've had horrible tube amps in sight, but who cares? I almost always listen in the dark and I did not buy them to impress anyone. Leaving this thread now, Roch Link to comment
