Sorry again, Duelund wire is from Denmark.
Best Way for my TT to reach my Pre-Amp!?
I have a Rega Planar 3 that sits a few feet too far away to reach my Marantz AV7704 phono stage.
whats the best way to reach my Marantz preamp processor with the short 2 foot phono cables that come with the Rega?
It sounds like rca extensions are going to cause too much capacitance and there is also a difference between phono extension cables and rca cables. Please teach me!

... as far as I understand, capacitance does not matter if you use a Moving Coil(MC) cartridge. The OP’s cartridge in this case is a moving magnet type. But regarding this point, generally speaking load capacitance is much less important in the case of a **low output** moving coil cartridge. But it can still matter, to a greater or lesser degree depending on the particular phono stage that is used, and generally speaking the less capacitance the better in the case of an LOMC. Lyra cartridge designer Jonathan Carr explained it as follows, in a post dated 8-14-2010 this thread: I should now debunk another myth regarding loading, which is that low-impedance MC cartridges are insensitive to capacitive loading. OK, the MC cartridges themselves aren’t particularly sensitive to capacitance, but the inductance of the cartridge coils will resonate with the distributed capacitance of the coils and the capacitance of the tonearm cable to create a high-frequency spike, and this spike certainly is sensitive to capacitance. In general, the less the capacitance the better. Having more capacitance (across the plus and minus cartridge outputs) will increase the magnitude of the high-frequency spike and lower its frequency, neither of which is good news for phono stage stability or phase response.

So just exploring I extended the TT phono cables to connect to the preamp using phono input selector. It introduced an intense hum only present on the phono input. Is this due to the fact that my rca extension cables are not grounded like the TT phono cables? Now remember that I have a Rega and the grounding is not done through your typical separate grounding wire. |
Craigert, Keep in mind that a typical 1 meter set of RCA interconnects will add roughly 100pf on their own... +/- 15pf. Some designs/manufacturers start out way higher than that. Since you say you make your own cables... I will obstain from any recommendations. I agree with finding a phono preamp with switchable settings... but would also recommend one that has settings for zero capacitance. Either that... or one that you can pull the lid and swap the capacitors and resistors manually. Some even allow a person to swap out op-amps. Be careful you don't fall in the rabbit hole at this point. ;) |
