I use an Audio Research ls28se Pre, in the past I used PSA m700 monos then switched to M1200. The M1200 really thump out the bass and that is what I was looking for as my speakers hold 4 12" woofers each. I have them and my subs running tru a modified mini DSP. Bass is very tight and controlled.
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.
