This KGSSHV CARBON is superb!! Great price, excellent build quality, fantastic sound! Paired it with L300 Limited Edition, L700 MK2 and 009S, they sound absolutely stunning! I am so happy that I bought this amp!
Fantastic service provided by MHF too, Vance has been very patient answering all the questions, thanks a lot! It only took 4 days shipping to the States, which is the icing on the cake:)

Purchased the L700 Mk. II and KGSSHV Carbon together, probably my favorite combo ever. I think I’ve found my end game.
Vance is very patient and knowledgeable. I highly recommend buying from him!

Nicely built amplifier for the money. I ordered the stock (no upgrades) Carbon and have no regrets buying this amplifier. It took about 3 weeks to finish the build after I ordered, but it was also during Christmas and New Years, so perhaps that’s why mine took longer.
This seems to be a legit KGSSHV Carbon, with tons of power. I usually listen at less than 10-11 o’clock volume. I’d recommend using a balanced DAC with XLR outputs for this amp.

I have been using this amp for almost 6 months now I am very confident to say that this amp is the best electrostatic amp I’ve ever owned, my STAX 009 sounds better than ever! Amazing build and sound, I am very pleased. The service from MHF is second to none, highly recommended.
