I've done it with a Voyager GAN 300 wpc class D amp with an Aric Audio Motherlode II tube preamp. Now am running the combo of a PSAudio M1200 class D hybrid monoblocks driven by the Aric Audio Motherlode XL tube preamp. The latter combination is the heart of my reference system and, for the record, it sounds heavenly. I have had awesome solid state amps - the JC1 Prarsound monoblock amps for example - but I don't miss the sonics of those backbreaking boat anchors because of the outstanding Audio reproduction of my reference systems.
Tube Pre/ Class D Amp - Who has done it?
Open forum for those who have actually tried this. Really curious to know who has been happy, or maybe unhappy, with a tube preamp driving a Class D amplifier?
Of course, tube pre with a solid state amp is a classic pairing for hard to drive speakers, especially ESL's. This is a little different. I'm really curious to know what pres and Class D amps have had great synergy.
