Okay. I'm fast becoming a Russian convert. I have listen to about 12 hours since yesterday. They seem to tick all the right boxes. Dynamic and clean. Can I hear a tad of mellow mid-range and slight treble roll off???? If so I like it.
Hi again Badas.
With further burn-in on the 6N13S I agree they tick a good many boxes - especially for the price! In my new amp they are driven by equally 'cheap' 6H8C drivers and this Russian combo certainly can deliver the goods. If you're interested, I gave my initial impressions in more detail over at the 'Feliks-Audio - 6SN7 + 6AS7G/6080 prototype' thread (so as not to fall foul of 'multiple posting' rules!).
MERRY CHRISTMAS by the way....
