15 foot RCA cables out of TT with no pre amp?


Im very limited with the space I have. This is kinda limiting me to keep the turntable on a 15’ cable. I’m using a Pro-ject Carbon Debut Evo with an Ortofon  2m blue to an Onkyo stereo with a phono input. Cables are midrange, nothing special but not total crap. Just wanted to get some opinions or suggestions on this. How bad the loss is gonna be if there is any.

As a temporary set up, if possible.
Place the Onkyo as close to the TT as possible and use a shorter IC.
Does Temporary arrangement require a Longer Speaker Cable ?

If it works you can then Try the Long and Short IC configuration.

Using a separate Phonostage, as already suggested, with the Onkyo will also offer other configuration options.  
You will be screwing up the high frequency response of the cartridge using a long cable. There are many inexpensive phono stages you can buy. Put it by the table and run the long cable from it.
Keep your turntable cable as short as posable and get a phono pre with XLR output you need a phono for that distance 
Doubtful the Onkyo has balanced inputs. If it does, XLR outs are a good idea, but would need a new cable too, and they are usually more expensive than their similar quality RCA counterparts. At the level of TT etc. you could pick up a Pro-Ject phono box for less than 100.00 and be good to go.
So, if I’m hearing this correctly. I should use the 1.23m cable provided to a phono stage. Then after the phono stage, the long cable will suffice?
