I'm taking the plunge into tube mono blocks I'm getting a pair of Bob Latino VTA M-125 Mono Block amp kits (never had anything tubes before)   so I would like you guy's though and suggestions on good inexpensive RCA cables for tube amps, one amp will be about 2' away from the XMC-1 and the other will be about 4' away Thanks Mitch |

This is what I use this Mogami to make my own RCA cables. Be mindful I do not use a preamp. These amps are perfect candidates for passive preamps and that is what I currently use. I use Switchcraft connectors. |

Should I use a subwoofer cable or a digital cable?

Treat the same as you would with Solid State. A quality shielded RCA cable. Tough to miss. Some of the Emotiva cables are cool, Mono Price, Blue Jean, just about any will do. Your budget, and preference figure in after the basic must haves such as a good Ferule, quality soldering, Shielding. Most do this already. Like I said, tough to miss.

What do ya think of XLR TO RCA Cable, XLR out from the XMC-1 to RCA in on the amps

Skip monoprice, Blue Jeans cable is great quality at a good price.
If you have some suitable emo cables, fine.
RCA to RCA.

RCA cables are RCA cables. Emotiva makes some very nice ones.

Indeed..... About the only kudo is about tube equipment. Virtually all solid state preamps have a relatively low output impedance, which means that they are pretty much immune to cable capacitance and noise pickup, and the same is true for sources (like CD players and phono preamps). However, some tube equipment, and especially vintage tube equipment and tube equipment using "vintage designs", may have a very high output impedance. If you connect a cable with relatively high capacitance to such a device, you may get a rolled off high end. And, if you connect a cable with too little shielding to it, you may get more noise pickup than you would with a cable with better shielding. This is the norm for real vintage tube equipment, and is still common with some modern tube phono preamps. (This still isn't a problem with most "normal" cables, but you do need to be careful with "audiophile interconnects", some of which have very high capacitance and/or inductance, and with very long cables.) RCA cables are RCA cables. Emotiva makes some very nice ones. |

Note that potentiometer-based "passive preamps", like vintage tube preamps, have a rather high output impedance... and also usually one that varies depending on where you set the volume control. Because of this, if you use a cable with lots of capacitance on the output of a passive preamp, you will tend to experience a loss of high end, and it will vary with the volume setting. Passive preamps that use autoformers (transformers) are also sensitive to the cables you use, because the transformer interacts with the capacitance and inductance of the cables. In that case, however, not only will the frequency response vary with where you set the level, but the interaction will be more unpredictable (rather than just a loss of high frequencies, you may actually get a loss, or even a boost, at some frequency, and that will change depending on where you have the control set). In both cases, passive preamps are much more sensitive to cables with excessive capacitance than most other equipment... and may actually sound significantly different with different cables. Most commercial cables should work fine, but, especially if you're making your own, you want to keep the cables as short as possible - to minimize both capacitance and noise pickup. This is what I use this Mogami to make my own RCA cables. Be mindful I do not use a preamp. These amps are perfect candidates for passive preamps and that is what I currently use. I use Switchcraft connectors. |

I use Switchcraft connectors. Precisely Keith! That is exaxtly how I run my cables and chose the specific Mogami cable I mention which has a very low capacitance! In addition, the cable length is only one foot from the DAC to the passive preamp and just two and a half feet from the passive preamp to the amps. The output impedance from the DAC is very low and the input from the amp is high so it works pretty good! I literally sold my $4,000 preamp after listening to my system with a passive preamp! Not every set up or situations will allow you to have all these variances in place to benefit from a passive preamp. However, I encourage anyone to do some research and experiment. |

I use Mogami Studio Gold XLR cables with my Jolida JD-502P amp. Never had any issues. With Mogami I do what the pro audio guys told me. Buy Once, Cry Once.
