Driving YG Carmel's

Tube amps would be the best way to go. The highs can be very unnaturally bright with solid state.

Thats just not true. Having used them with several amps and heard them in four systems not mine, all SS BTW, these speakers have the least sonic signature of any I have owned or heard. Also you need to listen to more of the better tube amps out there, they extend way up there, just like SS.

Stringreen, I'm with you on this one...

Not sure how much listening you guys have done with the Carmels, but my conclusions come from around a year of experimenting with them.
As far as the original question. I prefer tube amps with every speaker i have owned. The Carmels let them show better than any other speaker i have owned or auditioned.
Go for it! :)

Tom Hankins: Thanks for the info! I agree that the YG's are very revealing. I use the "Concert Fidelity" line of electronics to run the YG's (which are very revealing also) and with well recorded material the musical effect is positively "mesmerizing"! I was curious if any users of these YG's had tried a powerful SET. I believe 50 watts would be the least amount of power you could use!
