Equipment Rack Between Speakers...Good or Bad

@rauliruegas  

Thanks for the info. Much appreciated. I didn't see that earlier. 
Yes, we all shall enjoy the music, not distortions. I like that :)

I swapped out my metal turntable stand for 4 concrete blocks and the difference is a considerable upgrade. See systems pic.

I think the thread has gone a little off track.

OK, here’s one for you. If you have components or rack in between the speakers it’s not the end of the world. The most best thing to do is isolate the components, you know, since the potential for mechanical feedback from the speakers is quite high. The effect of acoustic waves on the components is less deleterious than floor-borne vibration.

@atmasphere  Just to follow up on the past post. I contacted Benchmark and their Engineering department confirmed the following:

Thanks for your patience. Yes, our units do support the AES48 standard.

As I mentioned previously, with my old Benchmark DAC3 + AHB2,  I could not tell a difference between using Bryston Canare XLR between the preamp + amp and Audience Au24 XLR.  The Bryston cost me about $60 about 20 years ago and the Audience was a few hundred used.

I contacted LuxmanUSA to ask about the AES48 standard and they are contacting Luxman Japan to ask engineering.

Just wanted to add this if anyone was interested.
