Speakers that disappear
After you do all of the above, turn the lights off at night, poof…speakers disappear. I’m completely serious. After hours of placement experiments, some room treatment, center seat of sofa in just the right spot, well recorded track, lights off an... 
Best current 845 Tubes
+1 for Shuguang 845B. My amp came with Linlai HiFi, their base intro level tube. OK but not distinctive.  The Shuguang 845B much smoother, with nice balance, good strong bass, warmer but still neutral midrange and clean, clear treble. Pleasant lin... 
DAC options to consider for Innuos streamer
USB to Denafrips IRIS to Pontus II via I2S, surperb combo for less than a Terminator.  
List Of Small Company Tube Amps
+2 for Dennis Had’s Inspire amps.  He designs and hand builds KT-88’s, 300b with WE tubes, and more recently 2A3’s.  $2k-$5k.  Goes by radioman731 on ebay.  If you can pick up locally in Cary, NC, he’ll buy you lunch, introduce you to a couple of ... 
Primaluna tube rolling 12AU7 Notes
Nice summary of brands and house sounds.  I concur with a least one minor difference.  I found a black plate RCA to be a real surprise performer.  My main rig is a Willsenton 23 wpc SET integrated amp.  (I know, ChiFi haters, but it stacks up very... 
Affordable Grounding
I don’t know what the wooden tube does, but I concur with @bolivarjoy, I had a dedicated line from the panel with true earth ground rod and hospital grade pure copper AC outlets installed. Digital source, 20 wpc 300b/845 SET tube amp and high sens... 
Has a Power Conditioner Improved Your Sound?
No, but a dedicated power line from main panel with its own true earth ground and upgraded AC socket sure did!   
I want to buy new speakers for 50,000 and see it used for 30,000, what should I do?
If you’re spending that much, go inspect in person, listen, heck even tote your amp and cables. You can afford the flight, a first class hotel, steak dinner with a bottle of Lafite to celebrate purchase with what you’re saving! Unless you hate the... 
Tube or R-2R DAC for Tube System
Try both, or three, or four! I alternative based music genre, mood, low level listening vs LOUD, and whatever I’m looking for that, day, night, etc. Integrated tube amps, a 300b SET, a 300b driving 845s and a vintage SS Crown DC300A, a superstar p... 
Looking for 5AR4 rectifier tube most like solid state
Lot’s of interesting comments/theories.  I have five 5AR4s and three different tube amps that they can run in.  Also have a Cary 300SEI LX-20 that is SS rectified for a slight basis of comparison. IMO the cheap Sovtek 5AR4 is the “hottest” of the ...

PSVANE Discussion & Impressions Thread
@alightronics found them on Amazon, very competitive pricing. Are data sheets available? One of my amps runs the 300b very hot, 550v on the plate,100mA fixed bias with 55w dissipation to output 20wpc. The amp was designed for KR 300B XLS super 30... 
Ebay selling my missing amplifier
Is it the Dartzeel being sold by CargoLargo for $14,999? I rode up the chairlift in Utah couple years ago with a guy who ran eBay’s fraud division.  They have a whole team based in Salt Lake dealing with fraud.  Counterfeiting, fake offers, stolen... 
PSVANE Discussion & Impressions Thread
I own four tube amplifiers, a tube pre/SS power hybrid, and a vintage SS power and preamplifier.  Actually five tube amps if I count my father’s HH Scott 222C that is in need of a full restoration.  I listen to all of them regularly except the HH ... 
Looking for RCA cables from preamp to amp?
Ditto Blue Jeans cables. Read their articles, good info on how and why cables do matter, make a difference sometimes, and yet you don’t need to spend thousands. Their products are designed well, made well, and inexpensive relative to $$$ “audio sp...
