I recently purchased two Avantone's from AAAudio. I ordered them
because they looked and turned out to be overbuilt. They are also
very repairable. The spider is very short and tight on my 604s. I
read here or on another site that the MXL mount was easily broken.
The Avantones came with an extra set of bands, but they appear
to be standard O rings available from any good hardware store. The
female threads on the bottom were cleanly done. They are very
simple but perhaps not as sexy looking as others on the market.
By the way, the tightness lets me hold the body of a 604 anywhere
along its length, permitting me to get the capsules exactly how I
want them and keep them that way no matter how the stereo bar
is angled and hangs them. He has a good picture of them on his
Ebay site. The guy was easy to work with in putting together a
nice package and excellent price. I e-mailed him about what I
wanted and for how much, and he e-mailed back a simple "Yes"
with his 800 number if I wanted to order. I had the mics, mounts,
bar, and cables via UPS within the week. He wrapped the shit out
of 'em too. Not a scratch.
