Tube Monoblock location? - Rack or near speakers?

Mike for quicksilver recommends that I place the mini mite monoblocks close to the speakers to minimize the speaker cable length. This will mean rca runs of 10 to 15 ft! This is contrary to everything that I've heard. I assumed that speaker cable runs can be much longer than rca and are less prone to interference and capacitance + resistance?

Any opinions would be appreciated.

Thanks very much, Atmasphere.

I thought as much as well, still, much appreciated.

Atmasphere,

You mentioned that a preamp having 600 ohm output impedance doesn’t necessarily mean it could drive a 600 ohm load. So, not being an engineer, hence cannot read the schematics, is there a way to tell whether a preamp can drive a 600 ohm load by reading the specification general given by the manufacturers?

I am using an Aesthetix Callisto Signature, which has an output impedance of 600 ohm, and I wonder whether it supports the balanced standard that you mentioned.

Thanks

Isolating the tube amp on the floor or the shelf from vibrations is what matters more than where it is.

If the speakers and amps are sitting on a suspended floor,work on the underside floor joists and stiffen them up.

If the speakers are on a solid concrete basement carpeted floor,I think the amps placed beside them will perform better than on a less solid stand.
Of course there are costly equipment racks that will prove me wrong.

Short speaker wires and longer balanced IC are the way to go for me.
