Class A or Class D solid-state amplifiers (modern designs)

Check out the new Topping PA5 Class D amp. $349! Clips at 110wpc@8ohms with 1% distortion. Uses advanced circuitry and has an input level control. Ranks just below the Benchmark AHB2 in SINAD at 1/10 the price! 

TCO is total cost of ownership--I'm guessing he means power bill.

TCO for class A should include the cost of back surgery.

Has anybody had the chance to listen to LSA Voyager and Starkrimson and Hypex NC400?

Hi, about 10 years ago I owned a class D integrated from nuforce. on the long run I was not happy with it (too dry, a lack of soul) and I sayed to myself: never again class D! but that is foolish. things have changed very much. a few years now a class A preamp is working together with a class d power-amp from a little company in poland named acuhorn. it is a joyfull combo and I am pretty shure it is hard to beat in this price-category. I was very skeptical, but because of the money-back-guarantee I ordered one acuhorn rate-amplifier and he is still making music in my living room every single day.

+1 for the LSA Voyager GaN 350.

It is very chameleon like. Lovely oldies like Ella and Louie, Leonard Cohen sound full bodied rich and in the room. Lessor recordings sound, well, Lessor. Great value MSRP $3000, a veritable bargain compared to many class A or A/B amps whose MSRP are multiples

Sound improved considerably by replacing stock footers with Nobsound springs @ ~ $35/4. Now under all my kit, including speakers
