Upgrade from Pass Xono - Recommendations
I'm not sure why you use a pc on the Xono. The power supply filtering on the unit is extensive. It uses more uF filtering than most power amplifiers. I'm betting it would sound better without it.The Xono's sonic limitations stem from the so-so ele... 
Behringer Crossover for Maggies vs Bryston
Yes I get the Behringer flexibility & I agree with Listener it's likley a good way to play. Some folks are not fond of the sound quality depending on their system. XO quality is less critical for subs so you could use either and move them late... 
Weaknesses of the Adcom GFA-5802 ?
Well I owned a GFA-5800 which was I think the same design but with fans for cooling.The bass was phenominal. Bascom King did the review of that amp and loved it saying it bettered amps selling many times it's price and he especailly liked the bass...

Michael Percy still appears to have these PK 3.3uF 50V BGs.http://www.percyaudio.com/Catalog.pdf 
STUPIDLY high resolution pure silver interconnects
As long as youre going to "twist again", how about trying 7Ns silver from these guys?http://www.liveacoustics.com.sg 
Pass Labs XVR 1 upgraded pot replacement ?
Well if tou open the unit up you'll see that they're PEC (Precision Electronic Components) 10K pots made in Canada and yes they are all the same value. 
Pass Labs XVR 1 upgraded pot replacement ?
The Hexfreds (or schottkys) didn't make a huge difference but they're easy to change and not expensive.Replacing the psu caps is not possible as some of the uF values are very large with no ready higher-end substitutes. There's probably something ... 
Who do you like for equipment mods?
For speaker repair of vintage stuff, I'd try Bill LeGall at Millersound. He's less of a mod guy. He's been around forever. I've never used him but talked with him & his website's amazing. 
Pass Labs XVR 1 upgraded pot replacement ?
Sadly the hexfreds are not a drop-in as the XVR-1 uses a bridge package not discrete units. Looking at the data sheet & the unit inside you've got about an inch of clearance behind the pots so I think you'll be ok fit-wise.The more problematic... 
Pass Labs XVR 1 upgraded pot replacement ?
One of mine's noisy too - use contact cleaner. I replaced the stock power supply diodes with hexfreds. I wouldn't replace the pots as I find I need very fine adjustments here and I'm not sure the typical 24 step pot or even a 32 would be discrete ...

Is a Power Wedge 116 any good?
After 30 years, I have found that power cable have given me the least sonic improvements in terms of relative value than almost any other upgrades and results are highly variable. I think there's probably something else that will give you more ban... 
Modded SACD player: SACD or Redbook sound best?"
I'm not sure how they did the double blind AES test but if they couldn't hear the difference, they're "doubly deaf". On good recordings, sound quality is noticeably better on SACD in terms of inner detail and highs especially. Music has more body ... 
Three Cheers for Pass Labs
I own a Pass Labs X0.2, an XVR-1-3 crossover, an Xono phono, a pair of Aleph 2s, and a Threshold S/550-e. Not only do they sound great and are well-build; they're all classics or destined to become so.When I was considering the crossover purchase ... 
break-in for Marantz SA-7S1
To answer the question I think 200-300 hours or so should do it. Mine was a demo so I can't be sure but it's always sounded good. I'm not sure what CDs and associated equipment other people are listening to when they say a Marantz SA7S1 is "too fo...
