...got to agree with John_1. The Vandersteen 3As are great with McCormack amplifiers. I've used the DNA.5, DNA-1DX, and presently the DNA-2DX, and I strongly recommend the the DNA-2DX. BTW, R. Vandersteen and Steve McCormack used to exhibit together and used each others products. DNA-2s can be found used for really reasonable prices, and IMO are definitely Stereophile Class A, but they've never been reviewed-- thus the low used prices. I compared (in home) the DNA-2DX to Levinson 331, and SF Power 2, and it was no contest; I easily preferred the McCormack. Happy Hunting. Craig.
