As a matter of interest or perhaps not

[Ken Pachkowsky]

As several of you know I had purchased a Adcom GFP-750 last year and used it for several months before trying a Tad 150 Signature Tube pre-amp.



At the time of the switch I was confident the Tad sounded better, specifically in terms of bass extension and imaging. I recently purchased 2 more of the Adcom preamps, one of which has arrived and is virtually brand new 6 months ago.



Naturally curious, I hooked it up to see if I had been truly objective or just had my head up my butt wanting the Tad to sound better.



I know several of us have these Adcom pre-amps. Trust me guys, you will never look back if you switch them out. The difference is more substantial now that the tubes have burned in. I am dead serious; grab one of these before the prices go up. He is selling a lot of them for a good reason. Get the Signature Model.

Won't do me no good... I am not currently running a preamp. I do wonder what you're hearing that makes you say that the tube job is giving you an extended bottom end....

"the tube job is giving you an extended bottom end...."

Sounds deep. Is that for pleasure or pain?

Mr. Talent... you are thinking of an entirely different discussion forum.

It's probably the sound

The wife agrees after a blind test. Quote " That sounds much better (smoother and clearer) to be exact". That being the Tad.

PS: The Adcom was used in passive and active modes.

For what its worth....

Let me know if any of you get one and post your impressions.

I trust you bypassed the EQ's for this? Or, did you re-EQ for each preamp run?

By bass extension I mean a deeper more controlled low end. The imaging is more 3 dimensional and yes, you read that right. It's not my imagination. I know your a serious skeptic.....but...

What my wording was... I wonder what you are hearing that makes you think there is deeper bass.... I am not skeptical that you are hearing a difference... I am skeptical that preamp amp A would add bass extension over preamp B. Especially between these two preamps...

Well, I think "add" is the wrong word. Perhaps its producing something that was already there but doing it much better or more accurately?

I do like my 750 but after doing a side by side comparison with my Musical Fidelity KW500 I found a few things that I did not care for with the adcom.

1) The adcom does not have great output(very low).

2) soundstage is "farther back" in the speakers.

3) low frequency is lacking extension.

4) even with my sumiko phono pre, output from the adcom was less than ideal.

When I did my test I only used the KW500's preamp to power a pair of Proceed HPA-2's and then powered the proceed's with the adcom.

The adcom is a decent pre but there are better.

It did serve as a very faithfull pre and I was very happy for the time.
