Which "tweeks" are more important

If you can dedicate, do - and put some Oyaides on the wall to cap it off. If you can't, that's fine too - get a balanced power unit from Equitech or BPT or...

I have also found considerable (but not consistent) gains from various isolation units (eq Aurios, Roller Balls) under source, pre and amp. Not the same for all the units - and even one can make a big difference. Approach this in conjunction with a look at the platform itself - most sound better on a thick chunk of wood, a few on stone. The synthetic shelves are very amazing.

I did all the isolation on my rack shelves which leads me to believe that unless you can get to the really high end, get something sturdy and then start tuning.

Last add has been some Sistrums under my speakers and son of a gun - those help too.

I had the electrician install an EP2050 "Waveform Correction Absorber". It mounts to the panel. You can read about it at:

This product was designed to protect and purify power for huge, high tolerance computer aided manufacturing equipment and is now being offered for home use. Great company to work with and very interesting product that both protects and purifies without any of the downside effects (and cost) of power conditioners ETC.

Hope this helps.
