I have the LCD-2r2 paired with the W4S Dac-2. My amp is the Bryston BHA-1.
The synergy between the three components is simply fabulous. dleblanc343 heard it for itself.
Energy, resolution, linearity on the entire spectrum of frequencies and with a bass to die for but yet with a warmer and smoother presentation than the Mjolnir. At least with the Mjolnir I compared it to. We will do another comparaison soon with more burn-in on the Mjolnir.
You really should consider the Bryston with your LCD-2r2 and the W4S Dac-2. It's more expensive than the Mjolnir but the sound, the build quality and the 20 years warranty justify it IMHO.
