Class D audio vs James Romeyn

D class will never be as good as A or a well done AB or a great tube amp.

I have tube amp/very efficient speakers in my other system.
This is a different project. I have Virtue audio Sensation in this system, need more power. It's a class D and I'm not unhappy, just need more power in compact package.

After some discussion, my friend loaned me his James Romeyn Class D mono block power amplifiers and I liked them very much.  They sounded much better than my Luxman 590ax Class A integrated amplifier.  The music was more open, detailed with much improved bass.  I was very surprised and could not believe it. 

I consulted with James and decided to buy his Hypex NCore NC400 dual mono block power amplifiers with 2 NC400 amps per side with the NC1200 power supply.  He recommended his Class D dual mono version for improved sound quality.

The amplifiers finally arrived and they were a step above his mono block power amplifiers. The sound quality from my Hypex NCore NC400 Class D duel mono block power amplifiers is amazing.  

My sound system sounds much improved over my Luxman 590ax Class A integrated amplifier.  I mentioned this before in previous posts but we removed the R141 chip from the 4 NC400 amps that allow increased volume setting from my Bricasti M1 SE DAC. 

I am hearing details, imaging and bass that I have not heard before. My system now offers breath taking detail, transparency, lack of noise, and excellent dynamics that I did not hear with the Luxman 590ax Class A integrated amplifier.  

I  purchased the Hypex NCore Class D amps from James Romeyn Music and Audio, LLC (James).  He was very helpful answering my many questions and I suggest you contact him for more information on his assembled Hypex amplifiers (he offers 3 models).

how old were the tubes in the Luxman?

My Luxman 590ax integrated amplifier was solid state.  Sorry, no tubes.
