Oh really? A class D can't be a pro or a hi-end amp?

This amp is a "marriage" between Class A and class D and it has got some excellent reviews

I have read one of them in the Norwegian magazine Fidelity. It´s not a pro amp but might point in one direction that will be followed by others. BTW it´s not the first attempt to combine Class A with D .

I have a pair of 1960's Webster TP12-1 PA amplifiers (6V6 PP).
I converted them into pair of mono blocks last year.
They still need some additional work, as one has a greater volume level than the other?
It is not a big deal to just adjust one volume control up or down.
But being a blatant 'perfectionist', the volume difference bothers me.

The DAP Audio DPA-2400 looks interesting. Lightweight and compact due to a ( probable) SMPS. Marketed as Hexfet class D. But why call it "Vintage" ?

I use a class d 750 watt amplifier in my living room.
I run it into a 18 inch bass cab and a 4 by 10 inch full range cab.

I had a pair of Crown CE4000 for the subs but sold them when I was in danger of losing the house.
Now I have a stack of older fan-cooled professional amps, with SMPS and FET outputs (surprising for their age). They have balanced inputs and plenty of power. And they sound GREAT IMHO.

I used to have a pair of Peavey DECA 1200 amps, which were class D. They sounded pretty good for bass and mids (which was where I used them).

I have, in the past. Generally speaking they worked well but just not quite as good as a home HiFi amp fidelity-wise. Certainly if you need the power they can be an economical choice; I wouldn't say any of them sounded "bad". It's just that I found that the differing priorities in Pro Sound and HiFi revealed themselves in the sound.

I wouldn't use home gear for Sound Reinforcement either; in fact I would say it's probably worse to go the other way. Although I did see Ravi Shankar live (in a concert hall, though) playing his sitar through an array of Quad ESLs (the original ones). Have to admit it sounded amazing, but that was many years ago.

If you're too young to know Ravi, you might know his daughter ... some girl by the name of Norah Jones.

Some amps can do double duty but then again those examples are not that economical.

Just got another Crown Comtech 400 installed in my living room and it drives a pair of JBL HLS 810's and a Paradigm sub very well. I tried the Comtech 400 on 2 different sets of speakers and the speakers are definitely the main limiting factor.

While amplifiers are important in the production of sound, the part with the room for the most improvement is the speaker setup.
