You could experiment going up the various line of conditioners (via dealer loaners) and determine where your needs are met, i.e. no further refinement in sound quality. For value you want to buy a conditioner that does what you require and not more;however, I believe many companies enhance the conditioning/isolation capabilities as they build units designed to handle more devices or more power,so that makes choosing a bit of a challenge. I don't think buying the top of line Furman would be a waste of money;in fact it will be a permanent investment that you can build upon with power cords in the future (of course you can do the same with lesser units).By experimenting I have found isolation via balanced power units(in my case Equitech) to be so beneficial for my Spectral/MIT system that I have 2 isolating units, one for analog another for digital. I realize I'm a 'bit' obsessive about sound quality but I dislike listening to orchestral music without clarity and find the improved dynamics and nuance very enjoyable with solo instruments such as flute,guitar,woodwinds,harp and horns. Obviously I have found isolation and pristine power to be the foundation of a great listening experience. Cheers.
