Tube Amp for Klipsch Forte IV's? Black Ice F-22 or Willsenton R8 with upgraded tubes?

spent some time today researching, if I go with the Willsenton I'll pass on their tube upgrades and go with a set from the store below, the owner seems well versed in vintage tubes and the actual R8 amp

would like an amp that runs EL34s and KT88s approaching 50 watts with the EL34s

I had the Forte IIIs and moved up to Cornwall IVs. 

I drove the Fortes with all sorts of amps of varying power levels.  

The Willsenton is a very, very good amp.  You should also look at Doge Audio. They use better parts than Willsenton--the owner/engineer left Jolida out of creative differences.  He puts really good parts quality in the Doge product.  

A used Primaluna could be competitive.  I liked one with my Fortes.  

Better still (but not integrated) is the Carver Crimson 275.  Klipsch Heritage swings, sings, and boogies with that amp. 

I am running my Forte IV with Quicksilver mid monos.  Mike makes great stuff!!!   40 watts is more than plenty in my room ....  that said you should definitely check out the Quicksilver Integrated Amp.  It’s 20 watts of EL 84 goodness.  Quality is high for the money.  

Sorry just re read and saw you are looking for around 50 w. ...  check out Rogue
