Over and Under Biasing as means for tone control
I replaced tubes in my push-pull monoblocs with a different type, and in an elder moment forgot to re-bias. Everything still sounded great. It was only a week later, when I upgraded a tonearm, that I noticed a slight but very discernible upper bas... 
Setting up 2 power amplifiers to setup at once help?
If the Polks have 2 sets of input terminals, you could try bi-amping them.You'll need additional interconnects. Not sure it’s worth doing but if you want to play... 
Rega Ania Cantilever Bent?
Go through everything from scratch. If not fixed, call the dealer before you bust something! Something is not right. 
Stopping Vibration from Walmart trucks
Clad the new iron fence with 8’x4’ sheets of wood bolted together on either side of the rails- a sandwich if you will. That way you can remove if necessary and not have to reinstall a new fence or take down the new one. The double sheets will be m... 
Does anyone care to ask an amplifier designer a technical question? My door is open.
Question: Tube Phono preamp. Would replacing the 1N4007 diodes (in bridge config) in power supply with HEXFREDs or Schottkys improve it? The bridge feeds a CRC filter which then feeds a tube regulator. Thanks.

Interesting. Love the Albinoni Adagio. The X1 reminds me of the older Decca C4.

I would never sacrifice detail and openness for warmth. I think the very nature of high fidelity demands we extract as much detail as possible. If the system is balanced and tuned, the warmth should be present by default. Harshness and distortion ... 
What separate tube phono stage do you use ?
@br3098 That would be awesome. Croft tends to use good but not great parts. IN4007s and RIFA caps. Due to the microscopic point- to-point handwiring, it’s not too easy to upgrade parts. And I have been there - replaced all the resistors in a Micro... 
The urge to tinker is awash. What TT might better mine and why?
Belts are elastic. Stylus drag is real. ;-) 
Tubes
Have a look here.https://www.radiomuseum.org/tubes/tube_ef95.htmlThere are black plate CV850 Mullards on eBay which look good.

Sure thing on speaker position. I was thinking of moving the rug! Fair enough if they are spiked through. I wasn’t sure.I enjoy Tidal streaming too but find, in many cases, my vinyl rig is more enjoyable especially with my collection of analog rec...

@dmix I believe the OP has the GN power supply.@uberwaltz Why not try moving your speakers onto the tile for better rigidity?

Seems like there are mixed reviews on your table. If I was starting from scratch, I would look at a 301/401 with new massive bearing and heavy platter in the right plinth with a top notch arm. I don’t know your budget but as a starting example of ...

@fjn I should also note that your preference for warm (i.e. colored) sound indicated by preferring the JJs may mean you will be happy with less ultimate detail. I’m not sure. I know that when I changed my JJs out for Telefunkens, it was like I’d c...

I have read good things about the Audionote/Goldring IQ3. For me, it's all about speed and detail and that is where the London(Decca)/Croft shines. Nothing you do in the chain afterwards can make that back. I've avoided adding another stage of gai...
