No but I own the SE2SE amp and they are built very well nice point to point wire and the sound is just wonderful . The 211 tubes have a very nice sound and drive my North Creek Manifest speakers to the best sound I have ever had in my system . I have had many amps and tried a few from audio buddies the NAT is the best so far . I also would like to here some of there bigger amps and preamps I am sure glad I took a chance and picked up a pair from audiogon a couple of months ago .
