Next Best Upgrade for Tidal MQA?
QoBuz.1000 Gb internet service.Wired digital interconnects only. 
Tweaks you got rid of because they were not effective (enough)?
Expensive Ethernet cables esp. Cat 6 or 8. 
Best 40 to 50k used speakers
If you are in a part of Europe that imports them. e.g., Scandinavia, I would go with a pair of Sound Labs full range electrostatics new.  
Can anyone recommend an FM Receiver that would play into a relatively high end system?
I have a 6' yagi antenna on my roof with a rotator. It was professionally installed. Pick the antenna first, then get a tuner next. The most expensive tuner in the world cannot make up for an indoor or cheap 'amplified' antenna. 
Long XLR cables - help me decide
Assuming you have true balanced connections, I'd buy sets of balanced cables from Benchmark Media Systems in Syracuse, NY. On their site they have some demonstrations of their cables versus others for magnetic interference, etc. If you DIY you can... 
To venture back into vinyl or not,...that is the question.
I don't know anything about turntables under $500. I'm sure that is lots of info on this site. I have 100s of LPS, subscribe to QoBuz, and use an SACD/CD player. However:Sometimes SQ depends on the LP mix and the CD mix. A friend brought over a B’... 
Adding a SS amp as a 2nd amp for my tube rig has been a plus
On my trips to Japan the really hiend crowd uses SS preamps (usually Accuphase) and tube amps (vintage ’tosh and Marantz, and I believe Japanese Triode brand.) They use lots of horn L/S - many are 16 ohm nominal impedance. They explain do not want...

richopp-Interesting. We repair and upgrade both ARC and Mc based on 40+ years of experience. Since Mc has gone to hybrids and multilayer circuit boards, they have become less reliable and much more difficult to repair. For example, in recent integ... 
Accuphase DP-78 doesn't read SACD layer
salc:I am an authorized Accuphase dealer on the east side of the Hudson. My E.E./P.E. repair person maybe able to help you out. Is the unit a US Axxis import or from another country? If the unit no longer under warranty or comes from another area ... 
What are you streaming tonight?
Biber in 24 bit 96kHz streaming on QoBuz.Following Ambient Music by Brian Eno. 
Best bookshelf loudspeakers under 10,000 for the pair
Sound Lab Ministats. They have a dynamic woofer and an electrostatic tweeter. Available in many wood finishes. Since you already have a penchant for electrostatics, you’ll be at home wit them. They are self-powered and do not have to be plugged in... 
Speaker upgrade question - Wilson vs Focal
Before you buy, just for fun, listen to a properly set up Sound Lab Majestics or Ultimates for your room size/configuration and price range, (even if you have heard QUADs, MLs or Magnepans and don't care for them....not the same thing) 
SACD player with variable output.
Make sure you get an SACD player from a company that makes it own transports and stocks the parts to fix them.  Accuphase does. 
Well maybe it IS my hearing
Agree with eisen0169 -I get my ears professionally cleaned regularly.In fact, I think one should get all one's senses cleaned or exercised regularly. 
Is it possible to have vinyl nearly noise free?
Got this idea from Hifi Critic magazine and it works.Freeze a couple of records (after giving them a machine clean if you wish) and then use a rather strong magnet to take out metallic particles. Use a brush also.Let them come back to room temp an...
