I have had more than a few amps in my 2 systems over the last 20 years. The one class D amp that I remember was a PS Audio--dont remember the model number. great sounding amp.. Fast forward to probably just last year. I picked up a NuPrime. sta-6 (discontinued ) The STA-9 is current offering. The STA-6 has a class a pre stage in it with class D output. It does get a bit warm. Certainly not your typical class D amp. I am really surprised at how good it sounds. Ive pared down and in my main system there is only one other choice for amplification a Bottlehead Kaiju.. and have to run the BH on a different pair of speakers with high sensitivity.. The NuPrime STA-6 cost. 449.. not bad surprising punch way above its price point. I think buying a pair of the Wharfedale EVO 4.3 on a whim and wanted to see what this dome mid range is all about --not many designs use dome mid. it just happened that this amp really likes the Wharfedales.
Competitive class D amp suggestions
I have been Class D fun since a few years ago when i bought my first class D amp. I like the concept, in general, and all the attractive features of this class of amplifiers. I tried 4 different ones, currently i stayed with one of them that i consider to be the best among all four amps. I do enjoy and like it. At the same time, my 5 watts SET amplifier (with more than 100 times higher distortion according to the specs) gives more natural and (surprisingly) notably cleaner sound (THD of the class D amp is 0.001). The soundstage of the class D amp is not so bad but that of the tube one is still better.
I remain attracted by class D amps though.
Any fresh suggestions on reasonably priced class D amps (i mean excluding non-reasonably priced class D amps, e.g., Merrill amplifiers)?
Any comments on non-reasonably priced class D amps are also welcome (so far i was not able to audition many class D amps and am curious if there are some which could really compete with Class A).
