Last year when I introduced 4 Hydras into my system I found that there was an apparent increase in signal gain (only because many of my demo tracks, I know exactly where on the gain control of my preamp to listen). I know that this generated much discussion as to the typical objectivist vs subjectivist debates as to how this could be so.
Having my entire system now wired with Sigma Series PC's (3 HC. one digital, 4 analog) as well as 2 alpha HC's for my subs, I feel that having listened now for well over 6 weeks (and having introduced each PC prior to that serially over the course of the previous month that I can reasonably and safely say the following......"with each Sigma PC or a pair thereof I found that there was an apparent boost in the bottom end of my system. By the time the last pair of Analog Sigma PC's were added (to my preamps) I can say that the boost in gain was no longer a suspicion but fact. It is easy to hear the difference both before and after the introduction of each Sigma PC. Now of course I have opened the flood gates of prove it to me and all I can say is that is an observation that can be easily heard. In fact the bass response I was getting in my room made me stop and wonder how this is so with my 30 wpc amps."
Now this is obviously not a proper way but at least it is my way, "I use my ears" and have let them guide me in this hobby. For those who have heard my system before and after the change everyone always comments about the bass response in my room. Now of course this could be a case of the "Emperor's New Clothes and perhaps everyone was being kind.
So hear is the reason I started this thread. I was just speaking to my good friend Marty who has just introduced a single Sigma Digital for his TacT and is burning in a second for his Meitner player. Most of you here know that Marty has a TacT corrected room and IMO it is one of the best rooms I have ever heard. Having visited Marty on many occasions I have watched him correct small parts of his room frequency response and know how zealous he is about this. Well Marty told me that his room response had to now be corrected for bass because of the significant change in bass response.
So after reading all of this..."Is it possible that a Power Cord can alter gain in a sound system?"
I felt that Marty's observed change in his TacT room curve gave at least some credence to my observations that each time I made a change the bass in my room improved to the point that made me wonder how a 30 wpc amp can create this change
I don't know if it is the filters that Caelin uses or his comments re DTCD or just ?????
Perhaps Caelin and Marty might chime in
BTW, the final change to my system was adding the Alpha HC to my subs so people can't accuse me of changing the subs first
