    Got my Vincent in the mail yesterday and hooked and fired it up as soon as I got home. This thing is the TRUTH. Peeps on the forum hyped it and I kept putting it off because I'm a tool. Everything sounds better but the thing that floors me is how deep my soundstage goes now. It was always wide but the decay I'm getting now makes each not linger with a sweetness I'd only really experienced with headphones before. My speakers were impressive but Angel Olsen is taking them for a drive right now!

    Anyway, my main point for posting this is because I figured this might be a spot feedback and trouble shooting for the phono preamp. Since a number of peeps on the forum have it, or hopefully will have it! We can give suggestions and whatnot.

    Should I stack the power supply on top or on bottom?

    I put it on the bottom, but I don't know if that's "right".

    I probably should've gotten a cheap pre-amp to start out with so I could "hear" the difference with the Vincent. Right now, my system sounds great, but I don't know what difference the Vincent really makes because I don't have anything to compare it to! :)

    Like I said though, the solidity of the piece, the heavy metal frame, the obvious exceptional build quality... all of these things make me know that I made the right choice to get this beauty.

    I've got them on opposite ends of the turntable right now because I'm getting some noise when they're close to each other. I think this might be something @HiFi Guy recommended. Maybe my cables aren't shielded well enough because everything is tight and there's still some noise when the record isn't playing.

    I'm not sure how much real estate you have, but I think the idea is to place the power unit farther away from the TT, if possible. I have mine next to my UTurn TT - not stacked - with the pre-amp maybe 1.5" away from the edge of the TT, and the power supply directly on the other side of that so it's about 5-6" away from the TT. No noise issues that I can hear.

    It's something to try, at least.

    Ugh, can't wait until I have enough room to deploy something like this. Right now my Pluto is nestled in next to my Marantz with nary an inch to spare.

    Don't stack them. Separate them. If you have to go side by side, keep a few inches in between them and put the power supply on the right when viewed from the front.

    This puts the power transformer away from the phono preamp circuits- the point in having a two box phono stage.

    Edit: for cables- Blue Jeans LC-1. Low capacitance and well shielded- exactly what you want in this application.

    Should I get two? One from the turntable to the Vincent and the other from the Vincent to the amp?

    What would be the best option for grounding it then? Do I just peel off the ground cable that's attached to the stock cable that came with my Music Hall?

    You can do that or leave it be. The Music Hall is supplied with a quality cable. I'd just get the 1 LC-1 in your situation.

    This might explain the noise I'm hearing then. :) I can only hear it at very low volume levels, but it's definitely an intermittent tone, lasting a second or two, then going away, then returning.

    Guess I should've read the manual! :D

    Cool, I'll leave the cable as is in case I sell the Music Hall down the road. You can ground it with some speaker wire, right?

    The manual doesn't say much about placement. I figured it out by looking at pictures with the tops removed. If you are getting noise, it's either one of two things:

    Electromagnetic radiation/interference from the power transformer in the power supply chassis. This is the most likely culprit.

    Or- and this happened to me and I've not seen it before- hum when the ground wire attached to the Vincent but totally quiet when attached to the ground post on my Emotiva preamplifier.
    Oddly, my Shure cartridge didn't hum connected to the Vincent, my Ortofon did. My current cartridge is equally quiet grounded to my phono stage or preamplifier. If your amp has a ground post, try both places. Note: This will not be a solution for UTurn/TEAC/Rega or any turntable without a separate ground wire. Those brands are grounded through the RCA cables themselves, a perfectly acceptable practice.

    In a perfect world, you want the power supply away from your turntable (so your cartridge or cartridge wiring can't pick up interference) and the phono preamp chassis. When I had mine, I had both units on a shelf about 7" below my turntable, power supply on the right with about 4" between them. It was quiet even with a low output moving coil cartridge.

    I moved the pre-amp off the power unit. That intermittent tone I heard before is gone now.

    Awesome sauce! Thanks once again, @HiFi Guy!

    I've had my Vincent setup with the power supply to the right 3-4 inches away from the phono stage. Both units are 5 feet away from the TT inside my cabinet. I've been using these Mediabridge interconnect cables since day one with zero issues whatsoever.

    One of the best recommendations I received on this forum was the Vincent. Couldn't be happier.

    this is how I have mine set-up. you can see the PS is virtually touching my TT (on the right) and I have no issues with hum or interference

    Hit the 5 hour mark on the Vincent tonight. The bass just gets me in the gut. So good. Still some hiss/hum when nothing is playing. So I'm gonna pick up the Blue Jean cables and try and ground the preamp to my amplifier and see if that helps. I'll report back.
