There is a relative newcomer that Ive tried and had great (miraculous) success with, but hes not yet widely known. Alan at Alan Maher Designs (facebook) has a 2012 line-up he calls Quantum or Q. The whole AMD thing is different all the way around. He touts that the all-in-one box solutions just cant do a good job simply because they are all in one box. And that electrical noise has many points of origin scattered throughout the home and that, contrary to audiophile belief, its not dirty power coming in from the mains (unless you have an unusual situ of a large factory close by or some such), but its actually everything thats plugged into your home. Doesnt matter what it is, if its on or has a sleep mode (which pretty much everything does anymore), then its polluting your homes AC even your gear itself pollutes. Everything plugged into your home sees everything else and the noise from every source is bidirectional, so the noise is sent back to the breaker box which only serves as grand central for distributing it all over the house. Alan makes individual gizmos of differing types that are (easily) wired into the breaker box, or self-contained, wall-wart-sized filters that plug into various unused outlets in the house and various other devices that to an extent rely on the user experimenting with these locations for best audio (and video) results. In that sense, this is almost not an easy recommendation to make in that this whole approach requires familiarizing yourself with all his gear and a seemingly large dose of patience and willingness to experiment (Alan is always there willing and able to help), so its not necessarily for the faint of heart. But, the results are absolutely fantasmagorical, beyond description!! Somebody else once said of Q that it was like upgrading all of his components - and Im here to tell you thats exactly what it is. Also, this is the ONLY method of conditioning to come across my radar that (in fact) stubbornly refuses to take something away from the signal in the audio band while reducing noise not even the slightest of sonic compromises anywhere. EVERYthing is made better and not just a little plus some things you just did not dream were possible with the audio gear have (not including Alans gear, I have a $5k system so its not a just a function of how good ($$$$$) your system is, I can promise you that). $5k and up for an all-in-one box?? NO thanks. Ive invested about $1200 so far and plan on at least half that again before its over, but its the best money I can spend on my system by that I mean any and all of my components its the core of my system in fact, it IS my system, really. Yes, Im saying its that good. I know this is basically just a long commercial for AMD (for which I apologize) and that I cant help but come off sounding like a drooling fanboy, but maybe that has something to do with the fact that AMD (at the moment, anyway) has no meaningful brand recognition yet, so few people at Agon may be familiar with Alan. But, since Q, Ive been officially off the equipment merry-go-round and entirely content.
As far as conditioning goes, Alan does not make audio products, his stuff only reduces electrical noise thats all they do, period. But, it works in whatever application you can come up with. A filter placed at the fridge keeps noise from the fridge from affecting the rest of the house (your system included) just as well as it keeps noise from the rest of your house from affecting the efficiency of the fridge. With power factor correction, your fridge runs physically quieter and noticeably colder for the same amount of electricity. It works. Ive tried it. I even use a $60-version of his solution in my 2004 Kia minivan that works on the cars computer. Im getting right at 50 extra miles to the tankful with better and smoother acceleration and shifting I sh*t you not. His products are as green and forward-looking as they get most of them draw zero electricity from the wall. (Personally, I believe that when this energy-starved world discovers what he knows, for better or worse it is going to come and knock his door down). Collectively his stuff filters ground, neutral and hot.
But, to get around to your OP, some of his devices are best for digital, analog, computer, video though each will also offer much improvement for other equipment as well. Ive only occasionally seen him draw distinctions between SS and tube amps with his gear, but feel free to take that up with him. If you do decide to friend him on facebook and go down the AMD rabbit hole, prepare for an extended stay as theres rather a lot to take in worthwhile, but time-consuming (you can always message Alan for anything). Alan is a roadie by profession, but has experience in reducing noise in professional environments as well and for him the audiophile arena was more or less an outgrowth of that. Alan IS himself an audiophile however. He has a very direct, take-no-bs, make-no-apologies style, but Ive come to rely on his instinct for cutting through all the smoke and getting to the real fire of anything technical (or much of anything else as far as that goes) but youll just have to take the time and check it all out for yourself. The rewards are positively huge - IF you find yourself willing to invest the time and trouble, that is. Best regards.
