Phono interconnects a must?

[jimbones]

I have never specifically used phono interconnects on my TT. I do use a very good pair of interconnects (Wywires). Is there any benefit to using phono interconnects over my set of general purpose interconnects?

[Folsom]

No. You just need them to be shielded.

Welllll also don't use high capacitance ones IMO in this critical spot.

[James Edward]

I had a similar issue/question.

Well, the 2 Jim's didn't hear anything objectionable so I guess I am good to go!

Just found this on Pete's site. I don't know if anybody here uses them.

  I believe you may be confused. If your TT has RCA outs then NO. Just use a shielded cable of your choice. If you use a true Phono cable it has a connector from arm then RCA to phono input. There are also cable that are directly connected to the Cart. I use Crystal Cable in the Kuzma. Solid Silver wire from Cart to phono input.

Bottom line, is that you should have a properly designed phono interconnect for your cartridge, especially if it's MM (Moving Magnet)!

When I was using my Clearaudio Maestro V2, I had specifically designed a shielded TWL phono cable that MATCHED the cartridge and phono input. In the case of my Clearaudio cartridge, I had 220pf of total loading capacitance. My tonearm wiring was 25pf along with my TWL interconnect of 95pf together with 100pf of the phono input, these capacitances formed a parallel circuit with a total sum of ~220pf that basically guaranteed an exact match for my cartridge (and most moving magnet cartridges). This balances the cartridges' inductance which is usually in the region of 500mH and the 47K input resistance controls the overall resonant Q.

Extremely important since if the overall capacitance is too low, you would have peaks at a higher frequency, causing upper midrange losses (The midrange is where you live!)... Too high capacitance, you would have peaks in the upper midrange, causing high frequency losses!

I remember SME having a high capacitance phono interconnect and those using a MM cartridge were caught off-guard not knowing the cable was designed for MC!!! Moving coil cartridges are much more forgiving!

So the lesson here is to have a properly designed phono interconnect to match your cartridge!! Don't forget about that!

I have a LOMC (Dyna 20X2L) and VPI Classic with RCA'a if that matters.

You should be fine with a quality shielded RCA IC...

[James Edward]

Phew!

[rollo]

   Pete does that not hold true with any IC used. Add up ones Cap. load and find a cable that comes close. Shielded a must.
