crazy bill the eel killer Ex Member	Re: DFR8's Reply #30 - 05/19/06 at 17:07:55 Hello Rob, Wait till you hear the cyroed versions. Unbelivable!! BTW, if you don't mind, where did you source a case of fifty at that price. Also, do you have a tube tester to match your pairs, or do you find it's not an issue. Thanks, Bill

Another interesting thing you might want to try:
Mount the ribbon facing the rear, and wire it out of phase.

I'm sure this 'rear ambience' effect would work better if it were mounted IN the cabinet, but I like the effect a lot.

What value cap are you using on the tweeter?

Bill...
The seller was the same one on E-bay who is selling the cases of 50 on E-bay at the "buy it now" price of $175.
At first he did open auctions on these cases, and I lucked out on one that ended at like 3 in the morning with only one bid ahead of me. I got it for $108

I do not have a testerand have never matched tubes in my pair of Selects. It's never been a problem, unless one of the tubes is bad, or at least way off from the other, and that has only happened 2-3 times in 5 years.

Brad..
I'm using the 1uf Mundorf Silver/foil from Madisound.

You MUST send them in for a good Cryo treatment - it brings these tubes to a completely different level. We did a group Cryo buy/treatment a while back on these forums. Everyone really liked them including Steve.

I have 16 of them being treated as we speak :)

Rob where are you having the Cryo done and how much is it costing you?

It sounds great! A little more efficient, more midrange detail (as if there wasn't enough already!) while still sounding smooth and not bright, midrange is more "juicy" for lack of a better word, and a hair better bass. Only downside I can see so far is you lose allot when not seated unless you're clear accross the room. Putting something under the fronts to tilt them back could help that.

While these are not large enough for a "true front bass horn" I think they are helping the mids my compensating for some baffle step loss.

The "Target bowl" tweak is reversible/non-permanant. I used double sided aggressive out-door tape (the kind to stick address letters on a house) to affix them.

Btw, you might think I'm goofy, but this really does improve the midrange quality and "juicy tone". I'd love for somebody with a less live (better treated) room to try this and let us know how it sounds - especially the imaging. For me I don't lose anything, but my room is not the best for discerning imaging details.

Bottom line is I was walking through Target the other day and when I spotted these bowls, I thought... hmmm... interesing profile... and man that diameter looks close. Then when I grabbed a tape measure and saw it was 8" I had to take one home to try out. I cut the bottom out with a razor knife, and listened to it on just one speaker, listening mono, and switching back forth to compare to the other without the bowl. Things sounded promising and I didn't hear any major problems, so I bought another bowl to audition in stereo. Well, I don't think I'll be pulling the bowls off any time soon - except maybe to silicon them in place permanently.

I'm lovin' it even with my Charlize chip amp. I'm really chompin' at the bit to get my TABOO and CSP back from my friend!!!

One of those accidental discoveries. :)
