First Watt Sit-3 paired with Klipsch Cornwall lV?

Chorus-

If I had to choose right now... the XA25 would be out the door. 

If your Cornwalls are a flat 8 ohm load then try resistors on the speaker terminals to get it down to 4 ohms. The SIT-3 sounds best at around 4 ohm loads.

I don't remember which size resistors. Zu Audio would know and can make you a pair for your speakers.

I have Frankenstein Mk.II 300b mono's and a SIT-3 amp which I use with my Horning Eufrodite Ellipse speakers. I do like the 300b's better, but for SS amps they are really nice!

I have an analagous setup with Nelson’s First Watt clone Aleph J and Crites B speakers which I have enjoyed for several years now. Better than stuff costing 1000s more, collecting dust now :-(

10 ohm 5 watt?

I still have a set of the Zu resistors... thought they should be a different value
