I think that the manufacturer would probably have the most insight to that question, and I find them (Ofra and Eli) to be some of the nicest people in audio. I have the Avante Gardes, but I am selling them here in Audiogon. If you would like, please call me at 718-623-1935. I have heard these speakers on Cary tubes and it was a very nice match. Certainly the bass "grip" wouldnt be as strong as a well designed SS amp, but the sound was romantic. These are all aroung excellent performers. If I move into a larger apt again, then I will surely buy them again.
