I see no problem with providing an exit out the side of the enclosure to allow you route the wires, especially if that makes sourcing the enclosure an easier task. I'd just drill a hole in the side of one of those that you linked to, install a simple rubber grommet and be done with it. FWIW the ones that you linked to are exactly what I was thinking of.

Indeed!

What's the diameter of the donut?

On the beta22 there are at least 6 parts (4 caps, two resistors) per channel that would need to be switched. If you want to figure out a way to do that efficiently in a 4-ch balanced amp go for it, I'm all set. And I freely admit that there are other ways to provide a pseudo gain switch on the beta22 but that's only one of the things I listed that makes it a less than optimal preamp.

I listened to some of that last night, it's definitely one of my favorites.

Generally speaking I'd say I've found the beta to be the better sounding headphone amp compared to the M

Yet another company that appears to use this when writing marketing fluff.

I believe this thread serves as a good bad example. It's a dumb thread, as admitted by the OP, and similar topics should be avoided in the future. Community served.

Please, please tell me that the donut trafo isn't going to stay exposed like that. I mean I'm a champion of the industrial, no frills aesthetic but those transformers stick out like a sore thumb on what are otherwise gorgeous amps.

I think I've heard 2015 tossed around, which is a pretty long time in computer years. They certainly can't stop support on it when they release 7 or whatever they're going to call it. Christ, they have to call Vista friggen Mojave to get people not to pan it the minute they look at it.

You're right, you will. How about you read for the next week and then we'll see how you do.

I would not call selling one a month a market. Who knows how low the price would drop if they became available again but Todd almost couldn't give them away when he was selling them.

Yup, by ~$100. Perhaps the ebay hunters are sick of the "this is the last one from Joe's collection" nonsense.

No, you don't get it. You're acting like an ass and going to lose you posting privileges shortly if you don't learn when to just read and STFU.

Looking good Ian.

The specs are where you'd want to look. The M3 consistently performs better in Noise, Dynamic Range, Harmonic Distortion, IMD and Crosstalk. Don't get me wrong, the Beta22 is an excellent performer and a fine preamp but it is both expensive and complicated to build and to me seems like a bit of a waste as a preamp. I mean do you really need a 15W/ch preamp? That doesn't sound like a preamp to me? Also, it's much simpler to implement a gain switch on the M3 which makes it more flexible in switching between preamp and headphone amp duty. My current plan is to build a balanced, 4-channel M3. We'll see how far I get with that but right now it doesn't look like I'll get to start it before summer time.

What he said. Unless you insist on discrete components or need the power of the beta the m3 is the better preamp from a #'s perspective. Look at amb's own measurements if you need more convincing.

If you want a headphone amp and preamp I'd build an M3, not a beta22. That's currently part of my plan.

You sure about that? Taken from this pile of rubbish. I'm of the opinion ,given his current business venture that his post should have been heavily edited since it's probably his biggest advertising tool.

Whoa, you're in for quite a trip there. You know it's 7 books, right?

I'd be shocked if anyone was running a beta22 loaner program, that's an insanely expensive risk.
