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.

I'm running an ARC LS25 Mk2 pre with a DS225 amp.  It's not reboxed modules, it's ARC's class D design and sounds very tubelike.  I leave the amp on 24/7 and it only draws about 10-15w while idling.

I have been looking at doing a similar combination with Orchard and a Rumba Extreme.  

@erik_squires What amp or amps are you getting?

 

@lwin - I'm getting 3 way plate amps made by Hypex.  I'll be removing the passive crossovers and re-working them with the built in DSP capabilities.  It's not a straight conversion.  In addition to a white-paper redesign of the crossover I'm adding 2x 10" subwoofers to each speaker.

I've been using my LS7 tubed pre with a Classe D two channel amp for years and I genuinely love the combination. I've tried a couple of beefy A/B amps but the Classe seems to sound better at moderate volume, which is where most of my listening is done. When I do want to crank it up, no problems there either.
