Budget phono stage under $100, cheap but refined, does it exist?
Upgrading the NAD PP2 with a good, regulated power supply and discrete op-amp will put you in a good place. The PP2 (cost about $100 used on fleabay) can be run stock until you raise the funds for the upgrades. You can probably do similar upgrades... 
Help! Power question
@pcc67 it is clear that you are pretending to know much more about electricity than you really do. Please, before you get yourself or someone else hurt due to misinformation, stop promulgating this nonsense. The “phasing” issues you are yammering ...

Ummm, one of you is lying. How can the actual experience of one person be wrong?  
Whats your take on a NAD 3020, I truly believe it defined stereo and still does!
I’m happy to say that I use a 3020i and a 3225pe in a bi-amp setup and love them. The 3225pe drives the woofers in my Energy Connoisseur speakers and the 3220i drives the mid/high. They are basically the same architectural design, but the pe has a... 
What are "true" balanced connectors
@erik_squires Balanced signals used to be transmitted by transformer outputs and inputs which were galvanically isolated. Best,EGalvanic isolation isn’t a requirement for a balanced circuit. The transformer output, unless it is center tapped, is o... 
What are "true" balanced connectors
@erik_squires  Each signal is actually referrenced to ground,Not universally true. I should have said referenced to -signal- ground. That is the balance point that both signals share in common.  
What are "true" balanced connectors
Each signal is actually referrenced to ground, but the differential receiver only uses the two signal bearing wires to convert the differential signal back to single ended for further handling.  
Cartridge Mounting Hardware
While I don’t have the spec for my cartridge’s (Audio-Technica VM540ML) mounting screw torque, I’ve requested that of the manufacturer just recently. If I get an answer back, I’ll share it here.  
What are "true" balanced connectors
Balanced inputs are not defined by whether two channels of a stereo amplifier are bridged or not. The concept of balanced inputs is that the input is a differential receiver, where the signals on each wire are equal and opposite polarity. Thr diff... 
Do you ever do this before you listen?
I do that when I’m in a plane and the cabin pressure starts building as it starts descending.  
Cartridge Mounting Hardware
The correct way to tighten something is according to the manufacturer’s specifications. They know more about their products than anyone else does.  
Cartridge Mounting Hardware
Accuracy of torque wrenches is relatively unimportant compared to getting consistency of torque when it comes to tightening lug nuts (or wheel bolts if we’re talking German cars). There, a Harbor Freight torque wrench will suffice. On the other ha... 
What do you mean you “heard” the turntable
The law of diminishing returns will be where the line blurs.  
What do you mean you “heard” the turntable
@oldschool1948 said:I have a new Technics SL-1200G and vintage SL-MK1600 MK2.  With all things being equal except the tables, trust me, I can mostly certainly hear the difference.That comparison is not really apples to apples. The SL-1600mk2 is th... 
Group delay in subwoofers
Delay is caused by the velocity factor of electricity through the paths it takes. Wire and circuit board traces are generally the fastest parts on the trip, but still you need to take the aggregate length of both routes to know if one is significa...
