Amp Speaker Pairing


My amplifier is the Pass Labs XA 60.8 monoblocks.  These output up to 60 wpc in class A and from 60 to 130 wpc class A/B.  The room I use is a generous size 19’ wide, 32’ long with 9’ ceiling.  Looking at the WilsonYvette speaker, the website recommends a minimum amplifier power requirement of 50 wpc.  So my amplifier falls within the minimum qualified amplifier power qualification.  I am seeking input on the sufficiency of my current amplifier to drive the Yvettes “comfortably” (headroom, dynamic swings) in a generous size room.  Mainly listening to rock/soft rock/blues.

Pass Labs XA’s, if I had a room that was 19’ wide, 32’ long with 9’ ceiling, I’d be looking at Tannoy Westministers, or at least a pair of Tannoy Canterbury’s.

You have the room length to be able to take advantage of the bass extension the Tannoy’s possess, and that Tannoy sound stage.


Driving a pair of 4 ohm Yvette’s who’s sensitivity is only 86dB, in a 608 sq/ft room with a pair of XA 60.8 doesn’t make a ton of sense, reguardless of their headroom.

Now, an 8 ohm Tannoy Westminster Royal with a sensitivity of 99 dB and a Frequency Response 18 Hz - 27 kHz, even turned up those Pass Labs XA’s will be running in their sweet spot all day long.
Even the Tannoy Canterbury Sensitivity 96 dB. Frequency Response: 28 Hz - 22 kHz.


I haven’t heard the Yvette’s, but I did auditioned the Sophia II a number of years ago, driven by a Bryston 4B-SST, fed through a Sim Moon deck, and for the money...... I wouldn’t buy them, but that’s just me.

That said Chilli, take the Tannoy’s for a spin, you owe it to yourself, see what you think.
