no chance dude! I love that Dynahi and it took me a while with WTB to get earlier this year

I am not sure Dynahi boards are still being made anymore. If not, it will be of a class of rare, lengendary, reference amps.

when are the impressions coming? Dynahi vs Beta22?

Just got Beta22 working today. Will take some time. Also I'm waiting for a new OMZ with multiple outputs which will make A/B'ing much easier.

Hey guys, I'm new to this stuff, is the Beta 22 a DIY only amp?

Yes. you can config it either single-ended or balanced.

here is the AMB's website: http://www.amb.org/audio/beta22


search the DIY section here on Head-fi. Or ask Ti (AMB) himself directly for help if you want to build yourself. Headwize.com also has lots of valuable info on building Beta22.

Awesome, thanks!

Last question: What's the average cost for me to finish my built?

totally depends on what config you choose. This may give you some rough ideas (without case, misc parts): http://glassjaraudio.com/category.sc?categoryId=2

So, the verdict is in, definitely transformer interference. When it comes to transformers, distance is your friend! Lacking that, you need some serious amount of magnetic shielding, and it's not always straightforward or easy to do.

What headphones are you using to test that? I only ask because in my case what was not audible with, say HF-1s, was still clearly audible with my Ety ER4Ps. But I'm sort of OCD about noise like that.

Rough estimate, a 3 channel version w/ single power supply will probably cost the better part of $500 to $600, with a lot of that depending on enclosure choice and accessories. Also, I'd really have to caution you that if you haven't built much before that the beta would be a very bad place to start. There's at least a couple folks around here who thought it'd be easy and now they're stuck with builds that don't work that they don't know how to fix.

Rockhopper's group buy really is a good deal when you figure there's around 20 to 30 hours of labor in building one of these.

Sorry to keep asking, but is there any sound quality difference between the 2 channel and the 3 channel with one being a ground?

And also, does 2 channel mean that it's not balanced and 4 channels means that it's balanced?
