Recommended S.S. amp type for TANNOY 15'' speakers

IMO Tannoy Red/Gold 15" drivers sound best with PP tube amps, 30-60 Wpc.  But if you want to use SS I would recommend one of Nelson Pass' excellent First Watt amps.  My choice would be the SIT-2 and my second choice would be the J2.

Nelson Pass (and everyone else at Pass/First Watt) uses Tannoy's to test their amplifiers... so like @br3098  I suspect many of Nelson's amps could be great with your speakers.

I pair my Tannoy Legacy Ardens primarily with a Pass Labs XA30.5 with excellent results. It never leaves class A in my use. This amp isn't going anywhere.
If you're budget allows, the Pass INT25 should have no problem driving your Tannoys.

I listened to Steve Guttenburgs recent Audiophiliac review of
the Tannoy Cheviot. Gutt is a true disciple of Nelson Pass-
owning multiple pieces from First Watt and Pass Labs. The Chevvy's
sensitivity is 4 points under mine. He said the FW was good but his 100.5 Pass monos were way better.
I now have a Pass Labs XA25 on order.
Thanks for all your above help.

yakbob,

Which preamp are you using with your XA30.5?
