Opinions please on integrated for green mountain europas

I used a Joldia 102B with the Europas some years ago.  I remember it having easily enough power and sounding quite nice.   I later moved on to the Callistos and Eos Hx powered by HK Cit II for even better sound. 

tsugury,
excellent choice for your speaker! :-) I’m a big fan of Green Mtn Audio’s time-coherent speakers. Used to own the C1.5i floor stander before i moved to ribbon speakers.
The Europa is an easy load so you could get some fine sounds from even vintage amps (just like crgolfer wrote in his post).
I used to have the Jolida 502A 60W/ch - very nice sounding integrated amp esp. with the KT88 tubes i had in them.
Heard good things about the Rogue Sphinx & NAD 375 BEE but I've not heard them myself.

Try to locate one of Gilbert's Blue Circle Integrateds...the Dar perhaps.  Read of great synergy between the two.  I've not heard it however.  Good luck.  Regards.........

I used a Jeff Rowland Concentra (first gen.), and the system sounded terrific. I also upgraded to Callistos (also first ten.).
