Hi,

I've recently bought a pair of used Tannoy Dorset T185 (60W, 8Ohm).
I like the sound and I'm very pleased with my purchase.
The speakers are currently plugged to an old Pioneer SA-506.
I'm not an expert audiophile but I have the feeling that I can get more out of the T185.
So I'm now looking for an appropriate amplifier to combine with them.
I have been given a list of Denon amps, can somebody tell me more about them?

Denon PMA 860 / 1060
Denon PMA 1080R
Denon PMA 900V

Is the PMA 900V an integrated Class A amp?
What is the difference with a New Class A amps?


I'm open to take in consideration other models/brands, so any valid alternative is welcome.
Thank you very much in advance.
Musical greetings
