Harmonic Tech vs Acoustic Zen

Just a technical note, Jayctoy mentions he has HT PS cable.
This was original HT design and quickly replaced by HT PS II which is noticeable improvement......I have only owned the HT PS II.

Saxo---To each his own! All I can report is what I heard in my system in my room. I would have kept the Matrix if I really thought it was better but that is not the case. I had ALL of the cables on hand for direct comparisons. I did like the Silver Reference but as I noted, factoring in the cost, the HT PSII was a better performer. On an absolute basis, the AZ Silver could be said to be more open but not $600 worth of more open. It also, as I said, had a tinge of brightness. I think this is why when Stereophile reviewed them, the reviewer suggested not to use them in a system that was a little on the bright side already. You know it is really hard to make a Vandersteen sound bright so it had to have gone that way somewhat. But, as I said, it is all really system dependent. If that wasn't the case, we would all be using the same cables. One things for sure, not many people on this sight agree on much of anything!

Jayctoy, the only way to get more bass is to get less treble. Let's be clear about that. That means you want an interconnect with a rolled top end, like a lot of cheaper ones. I use a Harm Tech Truthlink on my MD100 tuner PRECISELY because it softens the upper octave FM birdies and thereby adjusts the spectral tilt for a less lean sound from this leannish tuner. Voila, more "perceived" bass.
ICs are passive devices...wires. They can't amplify anything...especially bass..........I used the Pro Silway II and Red Dawn XLRs fairly interchangably. Both were quite resolving yet not absolutely smooth up top. I then preferred the warmer, more forgiving Discovery Essence, but after a CDP mod, can now use the outstanding SPM for an incredibly resolving, clean presentation. It's all about resolution, top octave rolloff and perhaps a few dips and bumps along the way. I would expect the AZ stuff to be slightly more resolving and cleaner up top than the older designs, and in some systems maybe sound "brighter", which may or not be desired. Everybody has their favorite spectral tilt, defined mainly by transducer choice (esp speakers in a room), and synergized by CDP and amp choices, with ICs forming a quite minor frosting of the cake. Don't get too caught up in it....

Subaruguru, one IC can roll off the bass more than another, too...

Subaruguru your explanation made me forget about this
bass thing, good explanation,IAM LEARNING THANKS.
