Modwright PH 9.0X Compared to a Pass Labs XP-15
If you are considering the Modwright, have a look wt the Zesto Andros - its very musical, bit more free and open sounding than the Modwright. I have heard it hold its own against much more expensive phonos in the same system.  
Voltage regulators and input impedance
Why don't you fire off an email to Audio Research - their customer service is exemplary. Also check with Modwright - it may be very easy for a local tech to increase the input impedance of your power amp to 20k without impacting the amp. If this ... 
If my Kenwood KD decks can't be repaired?
If you have the KD990, as mentioned in your other treads, its worth repairing. They are becoming quite sought after - sale of one would easily cover the repair costs. Have you tried Time Step in the UK - they mod Technics, no reason they couldn'... 
Fidelity Research MC201 for an Ortofon AS-212?
@f456gt  Also don't forget at a lower cost the veritable Denon 103. It's very musical. Wouldn't bother with the 103R, for the extra I'd get a paratrace tip on the standard 103 later. I ran a denon 103 with Garott Weinz Parabolic on at Eminent te... 
Can cables have a shelf life?
They need to run in again. Also moving cables alters the sound - I have a tech friend who can demonstrate moving cables alters the signal using test equipment and software. So put them in and leave them running for a week - then recheck the curr... 
Fidelity Research MC201 for an Ortofon AS-212?
@f456gt  Thanks, it shows 11Hz but compared to what? Not sure how you get that. Effective mass of AS212 is unknown. Effective mass of AS212mk2 is 12-18g. The FR MC201 is 7.5g, no specs on compliance but MC202 is 8.5 @100hz NOT 10hz as used ... 
DS Audio Ionizer for analog Playback
Ionisers generate ozone in the process of generating charges - there are federal guidelines as to maximum ozone generation permitted. Apart from potential health issues you have to also take into account increased ozone levels can accelerate corr... 
Turntable sub $4k buy decisions too many.
@glennewdick  Really you should have another look at a Rega P8 retail $4k readily available for about $3.5k including free freight - plug and play. Brand new, even with a MM Exact or Ania, very musical. Much better built than your old VPI. If you... 
Turntable sub $4k buy decisions too many.
Bang for buck - buy a refurbished Sota from Sota. They can also fit your arm of choice. Alternatives Rega P8, Feickert Volare are great TT's. These are better sounding than the Clearaudio/Acoustic Solid/Oracle Paris options you mentioned in my ex... 
How far is your SUT from your Phono Pre/Preamp?
External SUT should be hum free - Use low capacitance shielded cable between SUT/phono Make sure SUT chassis is earthed to phono via additional earth wire  
Cartridge Force - Is a Little 'Over-Force' Okay?
@brian_stabinger  There are optional counterweights for your TT - see here https://www.henleyaudio.co.uk/Counterweight-Chart You can weigh your counterweight to check what you currently have, and might need from the chart. Alternately you can ... 
Audio Grail or Classic Hifi?
@cool_jeeves  If you are in the UK - I have worked on some Audio Grail restored 401's and they are excellent.  Have had some issues with classic Turntables parts out of spec. Personally I would go Woodsong if you can for the 301, alternately Gra... 
Audio Grail or Classic Hifi?
I fully restored a 301 to better than new and because of the superior bearing and oils available today it ran too fast - had to calculate the speed error and go to a smaller pulley. Since you are in the US Woodsong Audio does a complete restorati... 
Cartridge Loading.....Part II
Take a 30Ω cartridge and hook it up to an ideal voltage amp and then another one and hook it up to an ideal current amp.  Now take two AC microamp clamps and monitor the current output of each cartridge.  Will the currents be the same for each ca... 
Choosing the right SUT for my setup
 If you believe that cartridge loading does not matter, well then, forget it and be happy. Yes - I have a raft of highly regarded SUT's - and have experimented with a variety of top flight cartridges - from 3-40ohms internal impedance. What I ...
