Amp choices

I have JPS power cords.  The new PAC Black.  It replaced some higher priced Shunyata's.      

As mentioned the Aragon 8008BB is a fine amp, I would even say wonderful amp, that will drive just about any speaker out there.  Neutral and punchy with great dynamics.  If your 8008BB is up to spec with fully functioning power caps, toroidals, diodes, transistors, etc., then IMO, no need to move on to the Halo or any other amp.

Now I know what amps Sinatra is using. THANKs.

Nice speakers, they probably do deserve a better amp. The Aragon is a solid performer, and I would think it better than the A21, but I think both amps are mid-fi.

For a real improvement, you would be better off trying a high end amp from the likes of Pass Labs, Plinius, Coda, Wells Audio, or Clayton Audio.
High end speakers deserve a high end amp.

Yes they are nice speakers.  Thank you.  I was thinking about a more significant upgrade which would include a Pass 250.8 or a D'Agostino Classic stereo amp.  I think the A 21 might be a sideways move.
