Crack;Bottlehead OTL - Page 137

post #2041 of 5557
The Crack is pretty much the ultimate antidote for the HD650s weaknesses. It is fast, detailed, and has a touch of sparkle, where the HD650 can be slightly slow, muddled and lacks sparkle. I don't mean to slam the HD650s, they are still very good, and especially so when paired with the Crack. I'm just miffed at Sennnheiser for introducing them at a price point above the HD600s even though I think they are a step down.

What DAC are you guys running with the bottlehead?  Anyone using the Hifimedy Sabre ESS9023 with it??  How is the pairing?

I was running the HRT Musicstreamer II ... then upgraded to the HRT Musicstreamer II+.  The MSII is very similar sounding to the ODAC (I compared)... decent, but not earth-shattering.  The MSII+ is a noticeable improvement over them, and I'm very happy with it for the price.  I tried the Bifrost Uber at the LA meet last weekend... it's a slight step up from the MSII+, but not as drastic as the MSII to the MSII+.

Odd, I found the Crack + HD600 a supreme orgasmic pairing. This pairing with "special tubes" in place of the usual 6AS7 and 12AU7 suspects, my HD600 sounded better than I had it on my b22, few other OTL designs and the Woo line of amps up to the WA22 it was about on par. I never found anything special about the HD800 + Crack pairing maybe bit romantic sounding but was about it, the Crack's lush sound glossed over the HD800 detail revealing characteristics at times.

I'm not a fan of the 12BH7. I have tried three different examples, and they were all a bit slow and bloated compared with the 12AU7 variants I've had. My favourite is still the new production JJ ECC802S, which is an excellent tube in every aspect.

 

I do definitely agree when it comes to the driver tube though. While the 5998 is an undisputed favourite, I could absolutely live with any of the 6080 or 6AS7 variants.

Interesting. The Crack was actually the amp that led me to sell my WA22. Even with $500-600 of upgrade tubes in my WA22, I thought the Crack + Speedball demolished it. In comparison to the Crack, I thought the WA22 sounded thick, slow and lacking in detail. The speed, details and transparency of the Crack seemed like a revelation to me...

How would you describe the signature of the JJ ECC802S? Does it lean more towards the warm Mullard signature or the detailed Tele signature?

 

Also curious about the Psvane 12au7 variant if anyone has heard it.

Since everyone seems to have a difference in terms of preference in terms of tube rolling, what are the reliable sites that I can purchase from?

Blerg, sorry, but I've got better things to do than that sort of linguistic masturbation about sound signatures. It sounds plain good.

post #2050 of 5557
Lol. If it sounds good thats aplthat matterd
post #2051 of 5557
I've purchased tubes from a number of different vendors. They were all generally fine, but I would say that I've had the best customer service from Brent Jessee Recording & Supply, a/k/a Audiotubes: http://www.audiotubes.com/ Best regards, Adam

FWIW, I would agree about not going overboard in trying to describe what various tubes sound like. To be honest with you, in my experience the changes are generally much, much smaller than some would have you believe. And think about what it takes to compare tubes: 1. Turn on amp with Tube 1 in it. 2a. Let amp and tubes warm up until you hear undistorted music. 2b. [Optional: Arguably, you should wait until the tubes are REALLY warmed up, say 10-15 minutes or so.] 3. Listen to music until you get a good feel for it. 4. Turn off amp. 5. Let tubes cool down. 6. Remove Tube 1. 7. Insert Tube 2. 8. Turn on amp with Tube 2 in it. 9a. Let amp and tubes warm up until you hear undistorted music. 9b. [Optional: Wait 10-15 minutes until the tubes are REALLY warmed up.] 10. Listen to music until you get a good feel for it. This is just for a single A/B comparison. I don't know about you, but I usually need to do something like A/B/A/B/A in order to really hear any differences. How long between hearing music through warmed up Tube 1 and warmed up Tube 2? 10 minutes? 15 minutes? If I'm being brutally honest, I can't reliably remember what Tube 1 sounded like by the time I get around to listening to Tube 2. The one thing I do notice, and that I feel is fairly objective, is how noisy a tube is, and whether it is highly microphonic. Best regards, Adam

Can anybody explain to me why it is that my posts and IMs here on Head-Fi now lose all formating? My paragraph breaks just get tossed out the window, and everything becomes an uninterrupted and unformatted blob of text that is very difficult to read... Grrrrrrrrrrrrrrr, Adam
post #2054 of 5557

Do you have the upper toolbar in your textbox? There's a "Source" button there that can mess up all the formatting.

post #2055 of 5557
Nope. No toolbar whatsoever. I've posted a note in the bug report forum.
