Hi

I have been using a strip with Cary tube preamp and digital sources on a Furutech GTX-D Gold outlet and Pass power amp to a Maestro on the wall for a while now.

The combination seems decent but lately with some bass heavy recordings I have found the bass thick and boomy on extreme low bass notes. The mids and highs are fine and I tend to be sensitive to bright treble.

I took the preamp out and put it to the Maestro on the wall and this ameliorated the bass somewhat. Everything became fuller sounding but as a result, there was less low bass reverb (sounds contradictory?)

I suspect it is the GTX-D Gold. I am guessing if I replaced that with a GTX-D Rhodium NCF, it will tighten up the bass and hopefully eliminate the excessive low bass reverb. But in doing so, will the highs become too forward, hard or bright as Rhodium tends to be vs Gold?

Any experienced feedback from users who have tried the Maestro, GTX-D Gold and GTX-D Rhodium NCF is much appreciated.

Thanks
 
If your system has thick boomy bass, you can swap out wall outlets until the end of time and they will never fix your problem. Kind of like your car having a flat tire and you think if you change out the battery your tire will suddenly inflate. You are barking up the wrong tree IMO. You have system/room issues, not wall outlet issues.

How so, so true!
In the past, they tried to cure problems with interconnect cables, now they have moved on to AC power stuff.
 
I have a different opinion.
Most of time we tend to think the problem is in the room but it´s not. It is really in the system, and yes, the solution can be achieved doing some tweaks.


Saying so, and from my experience with gold vs rhodium (not the stuff you are trying), i think gold is far way better than rhodium. Much more natural.


I suggest you to try some other brand. But always the gold finish.

If his bass is as bad as he says it is, no wall outlet is going to fix that. You can't tweak your way out of serious bass issues that are caused by the amp/speaker/room interactions.
 
OK so I got the GTX D Rhodium NCF’s.

I have about 5 hours on them now. I have the Cary tube preamp and digital sources on a strip to the outlet. I have the Pass Labs power amp on the Maestro.

There is greater clarity, air and instrumental separation. Image outlines are also more distinct, but with less bloom and fullness - I guess this would constitute a minor negative. The bass has tightened up and there is more micro detail all round.

More on the downside, the treble has become "silvery" with a bit of hardness and brightness. There is more extension but the sound doesn’t seem like it has opened up yet and still sounds etched and shut in.I do hope the treble hardness and brightness goes away. How long does this take?

The GTX D Gold had boomy low bass but I liked the top end on that.

Overall, if I had to choose one among the 3 outlets, I prefer the Maestro so far.
 
Furutech Rhodium plating take a few hundred hours to stabilize. Give it a few weeks of constant use before making your decision.

That´s why i told you that gold was/is more natural

Yes, I realise that but the bass was awful on some tracks and made the mids muddy sounding and indistinct.

There is meant to be a Gold NCF later this year. I may try that if the treble doesn't smoothen out with further burn in.

What speakers are you using?
 
I would first consider playing with speaker placement and listening position, it does not cost you anything.
 
mep said:
Thanks. Are you using them with subs?

Nah, no subs. I think i have enough bass. The boom seems to be more an anomaly, only on low bass notes and with some recordings. The Cardas Golden Reference I have on the digital source seems to be exacerbating it although the mids and treble are fine.

Done that already - I spent much time trying the Sumiko method and things seem fine. "Ballad Of The Runaway Horse" seems fine. "Way Down Deep" on "The Hunter" too. I did a couple of bass tests ie. Chesky, etc and those seem fine too.

Pulling the speakers out seem to have minimal impact where the bass notes on those recordings are concerned. The first track with the bass notes on the 24 96 download of Tony Bennett & Diana Krall's "Love Is Here To Stay" seem boomy. I don't know if it's me or the recording. i am giving the recording the benefit of the doubt since it is a current one.

Consider reading about room treatments; bass traps, reflection and absorption. Jim Smith somewhere on here may be a source as well.

Hi,

Any improvement since then?

Yes, it has improved but it fluctuates. The highs get better then get worse. So i guess the burn in is not done yet.

I whopped a Cardas Golden Reference power cord on the DAC (I had a Cardas Clear Beyond there with the Golden Reference on the streamer) and it ameliorated the issue with the highs brought about by the GTX-D R NCF, making the listening more enjoyable and less of a chore during the burn in process.

There was less air and space between notes than with the Clear Beyond but a fuller more "golden" sound kind of like with the GTX-D Gold outlet but with more detail.

The boomy bass and bloat is largely gone and that I can attribute to the GTX-D R NCF.

When the burn in is done, i'll put the Clear beyond back on the DAC. hopefully, i'll get more clarity, air and space between the notes with no or minimal loss in body and the mids and no sibilance in the highs - that's the thought anyway.

All these tweaks and cabling are tone controls - just saying.
 
Ok
But if it was me, i´ll keep on the gold finish, and try to find the right power cable (or other tweak) to get things right.

I think rodhium, and silver by the way, do not go as deep in the bass as gold. So we have the sensation of better and more controled bass, but... i could be wrong.


Goog luck.
Looking forward your last conclusions :thumbsup:
