And if you are a connoisseur of fine aluminum lines and value form over function, the Crack's rough homespun look will make you cringe.But if you want warm euphonic gooey tube sound, then the only OTL that gives you even more joy from a price-performance perspective is the Little Dot Mk3. If you are a detail whore, then the Crack's treble smearing will set your teeth on edge. The Crack falls squarely within the former category.If you are a devotee of transparency, and worship at the altar of neutral sound, you are going to be disappointed with the Crack, and its tropical profile. Those that are warm and gooey, and those that are not. - Posts that talk about the state of the subThere are two flavors of OTL tube amps.

I still enjoyed it, because all of a sudden the Sennheisers had energy. And planar owners need not apply either, the combination of Orthodynmics and OTLs is one 'O' too many.But if you have a HD600 or 650, you almost owe it to yourself to see what this alternate OTL universe looks like, where the laws of transparency and neutrality are suspended and everyone's feelin' hot hot hot :-)I went through several solid state amps trying to get the HD650 to sound like I wanted them to before breaking down and buying the Crack (and also the HD600, which I like much better), and I have zero regrets.It's true that the stock sound is very warm and bassy and tubey. If you only possess low impedance headphones, or even worse, IEMs, don't bother playing at OTL Park because you will end up having a rather, well, feculent time.

You mean I can make this thing sound like whatever I want?The Tung Sol 5998 doesn't just make the Crack a very linear amp, but it has depth, detail, dynamics, soundstage. Wow.Then, I got a few tubes. It wasn't great with everything, but it was really really good with a lot.Then I put in the Speedball and it took clarity and resolution to the next level.

The Amperex is natural sounding through and through, if a little sweet. Not so good with the HD600, but the Amperex and Genalex Gold Lion are killer with the HD600. It really allows you to take advantage of the HD650's refined treble, and the combo has amazing extension and lifelike timbre. The RCA Clear Top is by far the most amazing thing with the HD650, because it's bright but never harsh or sibilant, always smooth and delicate.
