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 🍀.
