I'm a big fan of the RCA 12au7 black plate.  To me, it gives a nice bloom to the bass while still being detailed.  And they're cheap!

I should say I also really enjoyed the CV4003 but it died on me after a few weeks, and scared the **** out of me in the process.

 

Just finished the E80CC resistor mod and surprised at the improvements. I guess it just powers the tube as it's designed to, so I shouldn't be surprised. It's well worth doing. Mids definitely opened up.

 

Edit: Holy balls. Just listened to Death Grips - No Love and physically recoiled when that enormous reverbed kick came in. Crumbs! Monstrous.

Its such a simple and inexpensive mod perhaps deserved of a place on the BH Crack sticky list so others can benefit without having to re ask the question or rely on searching through the forum.

For those who have done the resistor mod/switch to 'optimize' the SB'ed Crack's circuit for the E80CC/12BH7.. have you noticed any change in the 12BH7/E80CC's tube's presentation in the optimized (12BH7) circuit vs the stock (12AU7) circuit?

 

In the stock circuit, I find 12BH7s/E80CCs to generally have a more forward presentation and possessing a more intimate (in terms of width) but larger (more depth and height) soundstage... relative to most of my 12AU7s).

What do you guys think about using 6SN7 on the Crack or have you guys used it before?

Totally agree and I wouldn't have known about it but for your post on here, Jamie. So, again, many thanks.

I have tried Kenrad 6SN7 with stock Crack with Speedball and heard nothing special to write home about but will try with moded one some time next week

Thank You!These are the tubes that i have for now and 6AS7 few 12AU7 and a bit of 7 pin tubes that i want to try with the CRACK as soon as a get it.

Although I haven't fitted a switch, I do know what you mean. With the resistor mod, I'm finding it to be more 'refined'. That may sound like a backhanded compliment but it's peeled back layers in some of my favourite music which I'd never heard before. It seems to perform miracles on the mids. While I really enjoyed the upfront tubey thrills of the E80CC, and probably most of all in the stock Crack in fact, I'm blown away by what it is capable of, when run properly.

Or you learn to blow things up better :D

I tried blowing up a bus once, but I burnt my lips on the exhaust pipe.

That's what you get going for sloppy seconds...

Got Matt's Crack and it sounds great driving HD800 using Philips E80CC and Tungsol 5998
