Could Class D really be that good?

There are plenty of low budget class D amps,integrated. If you want class D on another level such as AAvic 280 integrated you can get one for around $10 k 

I have heard side by side at audio gatherings in the last few months .

mmore power ,far lower noise floor because of many technologies and very natural.

one friend just traded in Luxmans top integrated for this ,

Boilder,pass labs Accuphase you name it even at $15k nothing betteredit in many to all areas . For one they use a nonmetallic cabinet ,No RF,no magnetism ,or vibration ,they use many Active Tesla coils to reduce noise in multiples .

Denmark audio group ,everything is built in synergy even their Ethernet switch, they all use similar technologies ,they change the sign wave for lower noise 

power supplies from Japan medical grade vs cheap switch mode types ,even on output special stage to ramp up current on demand as needed , their Axxis Forte series 1,2,3 has streamer,dac, and 100wpc integrated for $5500 very good ,

my brother has a whole system with the Borresen Loudspeakers in the Z series and Ansuz great Ethernet switch ,most people don’t realize,digital noise travels from house to house because it is not grounded, these guys solved this again starting with their own grounding methods and Tesla coils what a difference .

my brother had the $3k innuos Ethernet switch ,the $2500 Ansuz much better ,he traded it in and bought their mid grade D3 switch far better still ,and their cables are special, theD2 cables actually are active ground shielded to the switch,streaming now sounds like good Flac files or cd .thsts saying a lot , Their power cords and system cables are beating top Nordost and others and much less  $$

power cord same thing , I am very impressed ,Go out of your way to hear them .

i have heard all their X series speakers ,the $5500 stand mount with $1k stands can compete with any monitor 2x+ with Ease , i want  the X3 speakers but with new home addition and landscaping,not happening , Xmas 🎅 🎄 if I am lucky 🍀.

I just bought a Nad c268, just to experiment with class D and to use as a second, or maybe third set up. I’m not using a conventional preamp, but instead running two sources into the amp. The sources, a Music Hall A3 Analogue phono stage, and a Smls Pl 200 top load cd player, both of which have their own volume controls. Thus far, I’m pretty well pleased with the sound, although not as good as my class A or class AB stuff (Sugden & Accuphase). I ended up buying a second Nad c268 to try bridging, as my Tannoys are a pretty stable load @ 8 ohms, and 89 dB sensitivity. I'll see how that goes. I'm hearing the cheap c268 has a warmer sound signature compared to its big brother, the c298, although that one looks real nice too. The Nad c268 has all kinds of options for its use, great versatility. Even ASR recomended it, lol. Not many reviews for it, as opposed to the c298. Guess I'm a guinea pig. 😃

After years of running different amp / int amp combos, tube and A/B solid state, I decided to try a low cost used Class D Int amp from Bel Canto S-300iu feeding ML Ethos. After 3 months I remain blown away by the clarity, imaging, (add other superlatives here)... My journey is over...class D works well.

The gato dia 400s class d very good. 

I added a THD (%) scale, which corresponds to the dB scale, into the graph for comparing more affordable NAD C268 ($1k) and the Bel Canto S300iu ($2.5k) with the Fosi V3. As shown, the NAD C268 is comparable to the Fosi V3, but the Bel Canto is far inferior. Again, measurements do not mean everything, but the THD measure does give an indication of the sound clarity. I just provided you with the data in one place for your convenience, and it is your discretion how you interpret the data.
