So Much "Harshness"

I did not plug the TT-PSU into the conditioner when I tried it, just the other electronics. It still had a very negative effect on the sound when the turntable was the source.

Learsfool -- It seems to me that the resulting isolation between the ac grounds of the turntable and the preamp could be the reason for the negative effects you noted. That could very conceivably result in voltage differentials between the grounds of the two components, which could cause noise currents to flow between them in the ground wire of the phono cable (which has a substantial impedance at ultrasonic frequencies due to its inductance), from where they might couple into the lines carrying the signals from the cartridge, and cause intermodulation products or other effects within the audible spectrum.

I'm always leery about doing anything that would tend to isolate the ac grounds of components that are connected together with signal interconnects. Clearly it can be helpful in some systems, such as in cases where people have separate dedicated ac lines for the digital and the analog parts of the system, but it can also lead to problems with ground loops, voltage offsets between component chassis, and spurious noise currents flowing in interconnect shields or ground connections.

Thanks for the good clarifications, also, on multi-miking, re-takes, etc.

Learsfool, and then maybe its just that particular conditioner you tried. I've had a variety of conditioners in my system, a few did some of the things you speak of, others work wonderfully.

At the risk of sounding like Mr T, when we are referring to harshness, what assumptions are we working on, i.e. the extent of the complaints that folks are making about the degree of the complainers experience of harshness?

For example, in my responses I assumed a gross complaint, one that was a harshness readily apparent and objectionable on casual listening by an average neophyte, as opposed to a minimal harshness (aka edge) observed after careful listening by an experienced audiophile with good listening skills. These are two different things, are they not?

Tvad, for example, or Learsfool, are positioned to benefit from all levels of real improvement to their systems, but would a possessor of very modest equipment, and listening skills, benefit substantially from using, universally, things the same things?

I'm referring to fundamental improvements. When many folks complain, for example, that his new speakers sound 'harsh' to him, folks don't seem to often ask how the 'harshness' presents itself and to what degree. We simply tell him to buy some 'warm' wires, buy some tubes, ad infinitum, ad naseum.

Am I off base in this observation?

Harshness is a very general term. It is also a very common problem. It can result from lots of things as has been pointed out.

So the devil IS surely in the details when it comes to curing harshness. There is no single universal cause or antidote.
