D amps

bernal737 don't guess, try a great class D amp. Orchard Audio is running an amp tour. Join the list on their website. Listen 7 days and and pay shipping to next person on the list. Then post a small review. After doing this I bought an Orchard Audio v1.0 StarKrimson Stereo Ultra DMC amp. The amp uses Orchard Audio's proprietary ganfet modules.

Thanks,

I haven’t heard any on B&W, but I’m an authorized Vivid Audio dealer, and their founder, Laurence Dickie, designed the B&W Nautilus speaker and all of the tapered tube “tweeter on top” speakers in their heyday before starting Vivid. The sound signatures are quite close. 

I’ve paired the Vivid G1 Spirits with Aurender’s AP20 integrated amplifier, which uses dual mono Purifi Eigentakt modules, similar to what is used in the Mola Mola, and it sounds really good. I actually reviewer the Aurender AP20 with these speakers on this forum:

The sound is very transparent and engaging, and there’s enough drive to properly control the speakers. I’ve also used AGD Gran Vivace on these speakers which also do quite well. Both amplifiers are very linear, so if any added warmth, harmonics, or bloom is desired, this can be achieved elsewhere in the chain.

I’ve used Rotel Class D amps for years and years. They use B &O iCE modules. I have five modules, from five channel 250/500 watt models to extremely powerful 500/1000 watts modules.  They are beautiful sounding amps.  Love em so much, I’ve built my own 1000 watt sub amps using these modules.  I’ve also built amps using Pascal modules up to 2500 watts. Very expensive, but incredible sound. 

I have been using AGD amps for a couple of years now and couldn't be happier. Lovely sound driving my LRS+ with ease.

@hgeifman FWIW, class D amps vary in sound more than tube amps seem to. So having a bad experience with one isn't an indication that another will be the same thing. The Hypex and Purifi modules are sold as parts so you have to come up with a power supply and input buffer, which has a dramatic effect on how they sound. At this point IMO its pretty well demonstrated that some of those modules have been put in boxes by by people that don't know what they are doing.
