I hope I can save you from the mistake that I made.

I bought the NAD 356 amplifier, and eventually found that it did not have good sound quality, especially in the mid-bass region. My wife was especially annoyed with its "flat" sound and urged me to get rid of it.

It just seemed "washed-out' and the sound was uninvolving; nothing that was obvious at first, but in time it became apparent.

I also tried another NAD, an older less-powerful NAD 325, and it sounded much better (this was with a pair of very good PSB ImageT6 speakers).

I have had mixed results with NAD over the years; some models sounding very good and others quite mediocre.

For a really outstanding amplifier that will sound MUCH better, I suggest the Arcam A19.

You will find that #14 speaker cable from Monoprice will work very well.

I have tried a number of speaker cables from Audioquest and other companies, and the above cable works just as well.
