After reading all the answers to my question about the headphone output I decided to get the amp and give it a try and I'm glad I did, what a fantastic amp for the money! it sounds great with my vintage speakers. The headphone output seems to be very good with my Sennheiser HD650's, easily beats a Darkvoice 332 headphone amp and it is virtually silent, there's actually no hiss even with my ear up to the speakers and barely noticeable with the cans, which is impressive as my Yaqin MS-12B pre & Arcam 8p power amp combo had a slight hiss if you listened closely.
I bought the amp used with a set of 8 Mullard cv4010 driver tubes already fitted, are the Mullards a good choice?
After reading through the thread a lot of people seem to favour the Genalex Gold Lion KT77's I what wondering what are the main differences sound wise are between the stock EL34's and the Gold Lion KT-77's? is it a noticeable upgrade?
Anyway a new and very happy MS-20L owner here
