I think the 58X pairs very nicely with the BH crack, however I prefer the tone of the 6XX with the crack more.

Actually the 58X pairs really nicely with the ifi nano BL as well.

I have a pair of Beyer 880 600Ohms on the way. Can't wait! I will probably end up the 58X, too...

I've spent a bit more time with the BH crack+SB and found that it is a really good match with the HD6XX and HD58X. Using the A&K SPKM as a source, I'm starting to understand why are there so many recommendations of the BH Crack + HD6XX combination on the forums. The highs are effortless while non fatiguing, the mids are smooth and holographic and the lows are satisfyingly full as well. With the 58X, highs come off a little more exciting and the lows hit slightly harder, however it does lose some of those romantic mids the 6XX are capable of.

I'm now starting to think of what other tube combinations to roll to improve sound, but as it stands, the stock BH crack+SB+HD6XX/58X is pretty much hard to beat.

Besides the 6XX and 58X, I have also tried the ZMF Auteurs with the BH crack+SB. I do get plenty of volume out of the BH crack with the Auteurs but somehow i feel that the mids are too forward and the lows are not satisfying enough. Its like some of the ZMF Auteur magic is gone with this combination. To me, the Auteur sounds best out of the Glenn's EL3N amp!

Hi, I believe you have better amps according to other threads.

Anyone else had tried a pair of 6BL7/6BX7 as power tubes on the crack? I highly recommend it.

Be careful, you can only use 12au7 with this set-up.

Any particular brands you'd recommend? And would a 6BL7/6BX7 work if there was a 7n7 to 12au7 adapter?

No brands preference on Crack.

NO, you cannot use a 7N7 (0.64A, similar to a 6SN7, limited by the Crack transformer).

I'm currently running my BHC with a Tung Sol 7236 and a Sylvania 7n7 with an adapter [7n7 to 12au7]. Is this combo ok? I think it sounds fantastic, but don't want to damage anything! I am guessing this is safe normally, but the set-up you mentioned with the 6BL7 would change the power parameters to make using the adapter unsafe?

It's safe to use a pair of 6BL7 with one 12AU7/ECC82/7316.

If you like 7236, you will like this combo.

BTW, your current setting is safe.

Yes, I have the Modi 3 and it works well with my Crack and HD650 headphones.

I use another Schiit multibit with mine but it is out of that price range, I run Gumby to Freya to Crack. All 6sn7 tubes except for a Tung Sol 5998, I did away with the 12AU7 some time ago.
