What are those little stringy wires coming out of the back?

It's wire leading to harmonizer. You may see on photo (right side of Rack).

reduces EMI/RFI from Alien transmissions

I avoid hanging antennas off of my equipment unless it's attached to a tuner to specifically to pull in radio or television transmissions.  If I need harmonization I provide that with my vocal chords (to the best of my ability).

It works. I don't care how much crazy it looks.

If add this thing ( https://www.acoustic-revive.com/english/roomtuning/rr-77.html ) - will be much better.

For the moment sound of 2 STA-9 in bridged mode I like less than sound of 1 STA-9 in stereo mode.

2 reasons:

1. STA-9 in stereo mode was feeded by top Power Cable of NeoTech brand.
For 2 bridged amps I have to use 2 Power Cable (self-made) which are absolutely identical.

2. 1 amp I received only yesterday, condition - "from box".

Of course I can hear difference anyhow. 2 monoblocks have crazy dynamic, more control, I can listen music
on very low volume's level, LF is deeper.

2 pcs STA-9 in bridged mode with my self-made Power Cables sound more ... tuby in LF band.

1 more strange thing - I switched on air condition today. No whistling in right channel.

What are your speakers?
4 or 8 ohm?
thanks


Are you using Audio Physic Avanti 89db @4ohm?

I heard that the bridged ST-9 was not so happy with 4 ohm loads, any words on that?

Amazing where these "I heard that ..." came from.
By the way, it is STA-9, not ST-9.

I guess if I will install 4 STA-9, I can hear everything on whisper volume level.  :green:

Or for an additional $400 you can go with the K-38 for 400wpc x 4  :thumb:

I am already tied to explain - I can not keep ANY amp between my speakers. My Rack stays on left side, NOT between speakers. I need only mono blocks.

Then put a single amp in your rack on the left side and nothing between your speakers.  Does the K38 not fit in your rack?

That will be my next step, 4 STA-9. The sound of 2 STA-9 running in bridged mood sounds fantastic. Looking forward to have 4 STA-9.  :drool:

Red Cross near the Window - place where I kept Power Amp T+A. First problem - restriction with access to window.
Second problem - all these wires around Power Amp looks not good. Third problem - my youngest daughter used to jump
over the speakers' wires.

My idea - to hide even XLR cable to right channel under the baseboard.

Light green zone near the Window doesn't accept ANY large object. Soundstage ceases from degradation.
