Cary SLi80 amplifier - Effect of power tube exchange
You're half way there.  After the GL88s output tubes settle in, changing out the two stock 6922 Input Buffer Preamp and two 6SN7 Pre-Driver/Phase Inverter tubes makes a notable difference yet again on the SLI-80.   Sure enjoyed mine even more afte... 
Theoretically better to connect my subwoofer from preamp out, or from outputs on my amps?
+1 georgehifiAgree, use PreOuts.  Last thing I'd want to do is to route a quality amplifier's speaker outputs and signal into yet another layer of cheap electronics, connectors, and crossover inside a subwoofer, and then on to another set of speak... 
Disappointment with Pass Labs - I'm looking for something else
@opm, how open are you to demoing other preamplifiers before you mess with changing to other amps or speakers?  I ask because there are countless references to folks changing out the XP12 for the X22/XP32 -and/or- good tube preamps with really pos... 
Disappointment with Pass Labs - I'm looking for something else
@opm"it’s the cornwall III"+1 what @laaudionut said. Try a completely different preamplifier with your XA30.8. Also, I learned from Nelson directly he has a number of customers running really good tube preamplifiers with his amps too. Change the i...

@opm I have a Klipsch Cornwallopm, how old are the Cornwall speakers? 
Spotify HiFi worth signing up for?
This whole "when is Spotify going to offer Lossless CD quality" drama has been going on since their last beta test in 2017.  Members persist. The spotify community forum rumor mill says they will finally offer lossless "sometime late this year".  ... 
Tube Amp with tone controls for Heresy IV's
@jab All tube amps have tone controls, they are called tubes. Different brands have their own sound, from bright to dark sounding.Do you change your tubes out every time on sub-optimal recorded music or restrict listening only to the best recordin... 
Tube Amp with tone controls for Heresy IV's
"Basie" by Erhard-Audio $2495https://www.erhard-audio.com/Basie.htmlTone controls with tone defeat too. A buddy has the same unit in preamp form with tone controls. He's used this setup with Klipsch Hersey III and his new Klipsch Hersey IVs.  Even... 
rule of thumb: how long do you leave a tube preamp on versus turning it off then back on?
+1 cleeds, +1 jjss49Amps on last, off first. Waiting 30 seconds between preamp & amp too. Some may wait longer. This seems to work on my tube amps, preamp. 
rule of thumb: how long do you leave a tube preamp on versus turning it off then back on?
@wokeuptobose Past three tube amps both used and new, with new or NOS tubes -    Startup:  During initial burn in, with new tubes in my preamp and mono amps, they performed and sounded better after 45-60min of warmup.  All burned in now, right at ... 
Power Amp suggestion
@singhm1 Looking over your list, all nice quality built stuff. Guessing it seems more like an itch to change than your Bryston amps wearing out, eh?.   If it's all truly "less than 5yrs old", gotta quick question for ya.  How long do you leave it ... 
Magnum Dynalab tuner
@doug714 Which model is it? I sold my modded McIntosh MR77 that sounded real nice and prefer my Magnum Dynalab MD102 with a few upgrades.  Sounds nice, airy, decent stations and good signal around.  Sometimes prefer it over HD streaming late at ni... 
BS Node 2i: WiFi or Ethernet..?
It's about noise and the designer of any given streamer. It varies.   Wired ethernet -and- wireless connections introduce noise.   Look up Signal-to-Noise Ratio (SNR) and Wireless Signal Strength.Also, ref: https://darko.audio/2018/08/ethernet-or-...

PSVANE 12Au7 12At7 12Ax7 "-T MKII" 2020 production run of small signal/driver tubes
Great to hear on the caps, I do the same with my DAC, preamp, Mono tube amps. It was not until I upgraded the four main coupling caps in my tube amps (to something significantly better) did I really start to hear absolute definable differences (ma...
