Relocating turntable - question

edited March 31 in 2 Channel Audio
My turntable is currently on the bottom shelf of my rack, where it doesn’t get a lot of use because it’s inconvenient. However, that is the only spot on the rack that will accommodate it. It is currently connected to the phono stage on my Parasound Integrated, also located on the rack.

I would like to move the turntable, and only the turntable, to the top of my record shelf, which is about ten feet away. I’ve read that long RCA runs from the turntable are a bad idea because the unamplified signal is very susceptible to interference. Thus, it seems like my best solution is to buy a phono preamp, place it on the record shelf next to the turntable, and have the ~10 foot RCA run from the phono preamp to my integrated.

I’m sure someone else here has run into a similar situation. Is there anything else that I should consider before I go ahead with that plan?

    Seems like that will work fine for you. Is the record shelf stable?

    That is the best approach. For those 10ft interconnect runs, choose 'directional' type cables in order to minimize interference there.

    The record shelf is stable. It may actually be more stable than the turntable’s current location on my cheapo tv stand. The weight of all the records on the shelf stabilizing it and the distance from the speakers will probably be an improvement.

    Will take a look into the directional cables. Did not know that was a thing.

    Thanks.

    Basically with directional cables, the shielding is shunted to ground at the source end (not destination end). That way, any stray interference picked-up by the shielding gets dead-ended away from the destination component (i.e., doesn't flow into the input jack).

    Noise "drained" to the low impedance end is a good way to think of it.

    Ground is a very nebulous term. "Closer to ground" is a pretty good way to think of it. In wiring, it's really more correct to call it a drain than a ground. It helps to think that way and it leads to keeping the concepts easier to think thru what you're doing.

    Low impedance means it's not very likely to pick up noise. Very sensitive, or termed high impedance, means it is very susceptible to receiving the noise and adding it to the signal. So draining to the lower point, or output, is the desired normally.

    Inputs...impedances 10K on up into the megs...noise can crosstalk into. Outputs...50 ohm to maybe 500 ohm typical. Less likely to be able to "receive" the noise being drained.

    Have you considered using a wall mounted turntable shelf? There are frequently added benefits to going this route. Plus if you are otherwise happy with the current config, it may be less expensive.

    That's good info. Thanks for clarifying!

    Thanks for the info on the directional cables and their grounding properties. Ya learn something new every day!

    As for a wall mounted turntable shelf, my space does not allow that in a place where I would like it. Also, the RCA cables on my turntable (Technics SL-1200 MK2) are soldered on and very short... they wouldn’t reach the integrated from even the closest place I could put a shelf, due to the width of my tv stand.

    Maybe this adaptor could open up other placement choices;

    Thanks for the suggestion @Tony M I think I am going to go with placing the table on top of my record shelf with a phono pre. It’s just the best location for the TT, even if I have to spend a little more money to put it there.

    @jdjohn Do you know if Audioquest Evergreen RCAs fit the bill for directional RCAs? I don’t think they mention directional anywhere in the description, but they do have arrows indicating direction on each end. If not, do you have any recommendation for
    directional RCAs that are not that expensive for about 12 feet? Probably want to spend $125 or less, the less the better. Thanks.

    Those look to be very nice cables. I'd bet they are directional, but from what I read, they even take the shielding a step further.

    Look at the RCA's they have arrows.... Is that not directional?

    I’d never heard of directional cables a couple days ago, so just wanted to make sure ;) Thanks for your help.

    Thanks for checking it out. Appreciate the help. I’ll probably spring for a pair of these once I find a preamp.

    I have and very much like two or three sets of Evergreens. (3 feet each) Huge improvement over average dollar store cables, as well as Monster cables. :)

    You will like those, I'm certain.

    Nice! Glad to hear the positive feedback. I have Audioquest XLRs from my streamer to my integrated. They sound good to me, but I’ve never pitted them against another XLR.

    Even HDMI cables can be directional especially in lengths over 20'. These are usually used for projectors
