I like the SELs. I grabbed them when they were going for around $40 a pair. They were the flavour of the week here in this thread at the time. If you go back you can find the recommendations from HK... I think it was. Their good, a hair wanting in the bottom end but otherwise very very clean. I think I gave them a 100hrs before a good listen.
I'll give the Voshkods another run after another hundred hours on them. I'm going to solder together a dummy headphone load tonight so I can run the tubes without noise or potential headphone damage. If the tube burn-in is tied to the output level (which no one has been able to confirm) I can crank the amp up more - so long as the 1/2 watt of resistance doesn't start to run away and bad things happen(TM).
Got some time before I head to to work tonight! Time to fire up the glass...
I just use my Sony Noise Cancelers during breakin, I turn it up to listening levels. I'm swapping a pair of my 1980 silvers for a pr of SELs, so I'll give them a listen.
My 1979 Voshkods have fully broken in now - they are better then the 1980, which beat the 1983s, which beat the 1992s. The 1979 have a bit more liquidity in the mids. I have 1975s and some 1967 Reflectors with saucer getters on the way...and now the SELs! Oh what tube swapping fun!
