galacticmayan - I was in a similar situation owning Tannoy (Churchill’s) and intrigued to try a First Watt product. I emailed Nelson and he said:
On thing about our amplifiers, they all like the Tannoy products – not a surprise since that’s our reference standard. If you play them at reasonable levels, then the First Watt F8 would give you some of those qualities that people like in Triode amplifiers. If you tend toward neutral then the XA-25 would be an excellent fit. You can get more power easily, but I don’t think you would need it. best, np
I think 3 Easy comments are very astute. Like him I worried that the lower power at 3-4 ohms would prove to be problematic with the F8. BTW the Churchill are 94 DB efficient. Yours are 3DB less, so it’s effectively like half the power.
I’m fortunate, I have a 845, and a 211 tube based Set amps to compair with. Further, the buzz on Tannoy is they respond better when there is more power. So I opted for the XA25, glad I did, I don’t think the F8 would keep my happy (my room, sonic priorities, etc.)
Even playing large scale complex music at lower volumes, the XA plays admirably, even Nelson says the XA amp is neutral compare to the F8, to me the XA is warm enough. However at any higher volume, and given your speaker are down 3DB, I’m not convinced either is a match unless the room is real small, and, or, your volume is lower than mine.
Aside from the previously mentioned amps I’ve also got a pair of S60 Atma-Sphere amps. There is a lot of synergy with what a) 60 watts of power will do with the Tannoys, and b) using OTL tube amps. The palpability and transparency is to die for. As good as the XA is, the S60 drive the Tannoys better IMO.
For me, the XA is the right choice with the two your contemplating. All the best in your endeavours!
