Please explain this to me. The preamp "knows" what are cable artifacts and what is program material? How does it know what is an artifact and what is the music you want to hear? How does it remove artifacts that occur before and after itself in the signal path? How does it know what are artifacts from good cables you supposedly want and artifacts from bad cables you don't?
Sounds like voodoo.
Its not- the artifacts in any cable have to do with the overall impedance of the system of which the cable is a part. If the impedance of the system is low, the cable will have less artifact. This situation is not new and was solved back in the late 1940s with the advent of balanced line operation. In fact the balanced line system was designed specifically to eliminate cable artifact and it works at that really well as long as the equipment used supports the balanced standard (note- most high end audio stuff doesn't). BTW the low impedance thing works for single-ended too.
That is funny..because the first word that came to my mind was voodoo...vulcan mind meld? (RIP Spock).
IMO, I repeat, IMO< the preamp is the single most limiting factor to transparency in a high end end system.
This is not entirely true- what is true is that is *can* be if poorly designed. The best speakers and amps in the world are useless if the preamp is unable to carry through with the signal. But the lack of a preamp does not mean that the signal will be more pure! There are lots of problems with passive devices and apparently lots of problems with DACs and stand-alone phono sections such that a good preamp that indeed works correctly can correct a lot of sins.
I'm not used to hearing the effects of cables in my system as my preamp is one of the few in high end audio that supports the balanced standard. To that end:
1) has a low output impedance and not only can drive 600 ohms but will drive 32 headphones as well (the latter not required to support the standard)
2) ground is ignored and carries no signal current either at the output of the preamp or the input of the amp. This is where most high end audio preamps fall flat on their faces.
3) pinout- pin 1 ground, pins 2 and 3 are signal carrying equal weight (and don't fall for that 'cold' and 'hot' thing that you sometimes hear about - all that does is promote confusion).
If your preamp can do all this you can run really long runs of inexpensive cable. I use Mogami Neglex in my system, 30 feet of it. I've tried high end cables but you just don't hear a difference. Similarly, the phono cartridge is a low impedance balanced source if a LOMC version, so I run a balanced line there too and have the same benefit of no cable artifact.
The thing that gets me about this is that this was all solved 65 years ago but we still have people thinking that such isn't even possible. You would think that audiophiles would embrace a simple technology that works as well as this does but you would be amazed at the pushback I've gotten over balanced lines in the last 25 years... (FWIW we offered the world's first balanced line preamps back in 1989).
