Class D amps

"Alot of owners of tube preamps don't like the tube/class D combo"

I have a tube pre-amp and like the combo.

The thing is, you have to pick a Class D amp that is designed to work with a tube pre-amp (ie higher input impedance). Same true for other SS amps in general.

For example stock IcePower Class D modules are 10K ohm input impedance unbalanced. Not great for a tube preamp. Older BelCanto Ref1000 falls into this category. Many lower cost Class D amps do as well.

Wyred 4 Sound and newer (and more costly) Bel Canto ref1000m using similar 10K ohm stock Icepower modules are designed to work with a tube pre-amp. Input impedance of Wyred is ~ 64K ohm I recall. BC ref1000m is 100K unbalanced and 200K balanced.

The digital amp company makes a really good class d amp. They have a model called the 4800a which is being discontinued and the cherry plus is also a very nice amp from this company, I think if you are considering getting a class d amp you should put them on your short list, just my opinion, Kent

There are class T(TriPath) that I personally prefer over the class D.
Being a studio tech hobbyist, got used to clinical and clean sound to evaluate a recording quality. Learned to appreciate Sunfire class T amps for these abilities of thin details, instrument separation, speed and muscle power.
Amps such as W4S have high enough impedance to be driven by any tube preamp with ease. I would though recommend to use fully balanced tube preamps.

No, didn't come out of a "coma." I am new to audigon. I have only seen brief mention of Class D amps but never did any lengthy research.

There is a ton of info on A'gon about Class D amps.

One of my favorite topics.
