You have a headphone amp for your headphones. I would ckeck out the Prima Luna Amps in the 35-40W range. They are very nice amps and run on EL34,KT77,KT88,KT90 and bunch of other including 6550. If you need the 40 Watts for about 2K your good to go. 2250 for the 40W model with Genelex KT88 standard and included. You will drive the Gallo nicely with that and astill have your V200 for your LCD2
Thanks for the tips, I'll give them a look.
