Tube SS hybrid or either?
You can't play the mid/tweeter panels without the crossover but you can play the bass panels full range.

Hay Satie,
U R absolutely measurement correct. Rite on.
The issue is which sounds clearer & clearer at load volumes.
I totally agree that separating the drivers w/separate amps performs way way better.
But the issue is 2 get the clearest sound 4 the least amount of $$$$..
U'r way is definitely better than the straight single amp route,
But does all that $$ spent sound clearer than spending all that (exact same amount of $$) on ONE higher quality top shelf amp.
It doesn't. Try it & U'll hear what I'm saying.
Mags on a $50K single amp will dust Mags on $50k worth of multiple cheaper amps.
A better arrangement cannot create more CLARITY. I agree it'll sound better & more controlled than w/o but not clearer than one single amp at the same price!!
Start naming products. I'm familiar w/most.
Sorry, no offense please.
BTW did U get my stretcher reply. It wouldn't accept it so I put it by U'r T-4a discussion.
Qty (2) 50k bi-amped would sound even more outstanding if audio is worth say $150k 2 us. WOW
I have never owned tubes, but we had discussed using them to round out the hardness in the Crown amp that will eventually drive these speakers. I am open to either solution.
I would suggest you look into one of the tube Schiit preamp/headphone amps which are quite popular and are neutrally balanced without a high freq. edge common in SS preamps at this price range. You can get them new or used well within your budget. With some patience I am sure you can pick one up on the used market at a substantial discount from the new price. Look at HeadFi for for sale opportunities and an idea of pricing.
Another suggestion is the old Melos SHA and particularly the SHA Gold as a great option near your budget, but somewhat above.
Other options are the very old SS classics like the Classe DR-5 and the Accurus preamp
The Tympani IVs have arrived and are in their initial position 5' from the back wall. Pictures attached show the room setup in both casual listening and dedicated listening arrangements.
I am awaiting repair of the Adcom GTP-500 preamp to do the initial testing with the Adcom GFA-555. Then the Crown 5002VZ amplifier will be substituted for the Adcom amplifier once the Crown is converted from 240v to 120v.
I ask for your input in setup, positioning, room treatments and other topics that will enhance the listening experience. The goal, as always, is to hear the music as it was recorded.
You need to get feet for your T IV, There are stainless steel brackets at hardware stores that you can use as their predrilled holes happen to coincide with the spacing of the holes in the TIV. Get 3 sets of feet (2 brackets each) for the bass panels and a pair of feet for the mid tweet panel.
Keep the mid tweet panel separate from the bass panels, take the hinges off once the legs are on. That will prevent intermodulation distortion from the bass panels shaking the mid and tweeter.
Once you have the legs on you can arrange the panels in an equidistant arc. The deep bass panel would then be put at the sidewalls and roughly perpendicular to it. That should be a good starting point.
.
I have the feet but only enough for four panels. There are no holes drilled in the outboard bass panels.
When separating the mid/tweeter panel, should I unscrew the hinges from the frame or try to pull the hinge pins?
I looked at the panels again and there are only holes for the feet drilled in the center panels. No holes at all in the mid/tweeter panel, and the holes that are there on the outboard bass panels are in the center of the panel rather than on the outside edges like on the center panel.
If I am going to separate the mid/tweeter panel, it looks like I need 4 more feet and then figure out where the holes are intended to be. These aren't new socks, so I am not sure why they wouldn't show up.
Yes on the hinges the screws would come off entirely.
On my panels there are holes on the bottom for feet near the edges but they were not drilled through the fabric. you need to feel for them with your fingers. It is possible that your panels didn't have them drilled, but so far I have not found anyone with Tympani panels without the holes for feet on their edges. If they were not used then the fabric would not be perforated over them.
