3 Tonearms 1 preamp

Thanks everyone!
The use of a passive preamp is interesting as well as installing a home made switch with rca jacks. It may end up I do one of these options.What I was hoping is to find a product that was designed to do exactly what I need. It seems that the need for a device such as this exists in other applications besides turntables and tonearms.

Thanks CMALAK,
I was hoping for something a little more affordable. I am also happy with the preamp I have.

Good Point Veridian. This is the reason I posted the question. The problem is looked at from others and the solution is thought thru. I have one question though, how does a phono pre with multiple inputs arrive at this without switches, wires and jacks in the path?

Thanks everyone.
With my budget I think that the idea of adding a selector switch and phono jacks at the preamp is the way to go. I will get the switch and jacks from an old receiver. No real estate on the pre so I'll make a box that rests on top and will enter thru the rca holes once the jacks are removed and hard wire direct. If I ever want to trade to another pre it will be simple to restore to original. Anything I have overlooked or need to consider is welcomed and encouraged.

Thanks for the advice Heyraz. That will lead to the same problem at the final preamp. Maybe Veridian can comment on the results of his conversion with the addition of the selector switch. I am learning that most every change is a compromise in some regard.The simplest compromise is the financial one but it is also the most difficult to justify in these times.

Heyraz what you say makes good sense and that is what i've been doing. It creates problems with location of equipment to make it accessable and out of the way.Thought if it didn't sound good I could allways go back to cable swapping.
I will try the box I described a few posts back and hear the results.I'm pretty sure something will be lost but if I'm lucky I won't be able to detect it with my old ears. If I can hear it than in the trash it will go as it was going anyway and back to cable swapping. And BTW you or at least I would switch very often if it was easier. Since I don't have the one perfect needle, cartridge and tonearm some records may sound better with a differant approach.In fact some records do sound better , what works best for one doesn't allways work best for others.

Well to take the guessing out I will tell you I am using an ATP-12T with an AT-160LC , AN AT-1010 with a SIGNET TK7E and an EPA-100 with an AT-150MLX going to a UREI transcription preamp that has been custom modded by a shop here in town. Also use an ADCOM GFP-400 for now which has an excellent phono section.(my opinion)The reason for the 1 table with 3 arms is to thin out my office / listening room by removing some of the turntables I have. The custom plinth is an experiment using 3 layers of 3/4''in. MDF with 2 layers of 1/2''in. hardy cement board sandwiched between. Results are amazing. This is rock solid and I cannot hear any feedback at all. My room is 12 X 12 and can play very loud with no audible feedback that I can hear. That was definatly not the case prior.

never said it was high level or that I wanted to customize the sound. I guess that is why all of these items were purchased here.not good enough as they climded up. The Sp-10 mkll really adds to the flavor.
