Transimpedance has too much gain?

Send the spinstage back to the manufacture to check.

I said Ideally. Output levels are still in play. The Spinplay has an input impedance "effectively Zero ohms"

I have a Channel D Seta L Plus and am very pleased with it. The coolest thing though is recording records with Channel D's Pure Vinyl program. The Channel D units all have pass through outputs, outputs without RIAA correction which is then done by the computer. It is like taking your photos in Raw format. I get to raid all my friend's record collections! Recorded in 192/24 digital you can not tell the difference between the recording and the original unless I kick in the pop and tic removal tool. This one really works. It removes the pop and fills in with the preceding 10th of a millisecond of music.

The only turntables that use a single wire ground are the Regas. Otherwise, all you have to do is is remove the RCAs and solder on XLRs leaving pin 1 blank. Pin #2 is positive and #3 is negative. Channel D will also sell you RCA to XLR adapters. I do not like any unnecessary contacts in the way of the cartridge, but if you do not have a soldering iron this is a viable option. 

@mijostyn @lewm Thanks for that info on converting a tonearm to balanced.  I also discovered VPI sells a somewhat overpriced junction box that you can use to replace the RCA box on their turntables.

Key word is "overpriced." A pair of gold Neutrik male XLRs cost a whopping $10.00.

IF many LPs sound ’right’, you do NOT need to change the connectors on your Tonearm. No 1K prominence on many LPs, just some Rock, makes no logical sense.

I have that VPI junction box, mini-din in, RCA out. VAS rewired my tonearm. I like it a lot except it’s price, but over time ....

To use it, you need to change the connector on the tonearm wires (which evidently are NOT a problem now).

KISS, you could buy a returnable MC Phono EQ from Amazon, use it to ’prove’ it is the current phonostage, and to prove your cartridge/arm/cable are not the culprit.

This brand may not be respected, but it has variable settings, find answers, return it
