Pass X1 / X250 - how to get a bit foregivable ???



Hi, my system is

Pass X1/X250
Lindemann D680 SACD/CD
Jean-Marie Reynaud Offrande speakers
HMS Sestetto balanced signal-cables
HMS AC-cables
HMS Fortissimo Bi-Wire speaker-cables

Who has experienced "successful" system-
cabling to reduce the brutal honesty of Pass X1/X250
(or similar) amps in combination with highly resolving
speakers and high esolution source ?

Bad recordings are sometimes just very hard to take
and stress my ears. Also the overall sound of my system
tends just a little bit too lean and organic weight is
missing.

I did not try out different cabling yet, so any experiences are appreciated.

I tried out replacing (a) X1 by E.A.R. 864 tube pre,
(b) X250 by Manley Labs Snapper or (c) both, but the
lack in soundstage and resolution compared to the Pass
amps was so much degrading (sorry) the purity of the
original recording by adding content that was just not
part of the recording, that this was no acceptable
solution either, at least IMO.

Please, any hints/ideas are very appreciated.

The Pass Labs is good stuff. The X-1 and X2.5 are two of the better preamps I've owned.

My guess is it's not the brutal honesty of the music or even the recording at issue here. Most likely it's the brutal honesty of inferior or no AC line conditioning and ics and scs that induce time-smear. Either of these shortcomings will induce an ear fatiguing presentation that makes one run for cover.

Everybody has dirty AC to one bad degree or another and everybody incorporating a cd player (and dac) is subject to bi-directional digital noise that will make its way back into the AC, even back to the service panel and then contaminate your other components. The only line conditioners I can recommend are the Foundation Research passive, dedicated, and bi-directional (for digital noise) line conditioners which I've been using for 5 years and recently took on that product line when I became a dealer. If you do not have proper line conditioning and start to shop for it, be aware that some of the most popular line conditioners actually induce sonic harm rather than purify it. Proper is the keyword here.

Time-smear in cabling (ics and scs) is very common regardless of price. But cables that induce little or no time smear are out there and they make a world of difference. Several that come to mind include Audio Tekne, BPT's, Audience, and Speltz. And none of these will cost an arm and a leg.

Assuming these are two areas that need addressing and resolved you will hear a pristine musical presentation that will catipult your system to levels you did not know were atainable.

If these shortcomings do exist and you choose not to address them it really doesn't matter what else you do.

BTW, with proper line conditioning, the performance of the X-1 should be near identical to that of it's single-chassied little brother the X2.5 which I actually preferred because I did not want the seperate power supply and 6 ft umbilical cord that comes with the X-1 if I could not hear any audible differences.

-IMO
You could try upgrading to the 250.5,much better in the mids than the older model and kinder to less than stellar recordings.
I used to have the X350/2.5 combo. (Still own the 2.5). If it were me, I would upgrade to one of the .5 amps and keep the X1. I've noticed that some dealers are offering a generous trade in on the older amps. Also the Shunyata Aries S XLR's worked out nice with the pass gear. I still own a couple pairs.
I use a Supratek Syrah with my X-250.
This combo works well for me and gives a nice
blend of s.s. & tubes.
As Stehno says sorting the mains supply
and power cords is crucial.
I find the e.a.r. stuff a bit lean and
the Syrah is not exactly a 'cuddly' valve sound.
I found the snappers - a new pair right enough, less
than refined with a solid state pre-amp.
Only my thoughts but I never new how good the Pass
was till I paired it with the Supratek.
My speakers are AP Virgos which are not thought
of as the 'overly warm soundin..g
Very few things sound unbearable and most sound sublime
but I do tend to favour vinyl.
HT Cyberlinks ended the constant i/c upgrade saga once and for all and treating my room stopped me striving for stuff that I just can't afford - at least for now??
Just an afterthought, I used HMS Gran Finale speakers cables for years and still think they are fabulous cables but - the Pass did not seem to gel with them.
Regretfully sold them and now use Harmonic tech Pro 9+
which I'm very happy with.
Strange as my last amp of similar power to the Pass (Nu -Vista integrated)gave astounding results with the Grand Finales.
Never did get along with the matching i/c's - the network boxes or whatever had me switching between the 10 settings like a paranoid loon and they never seemed to give neutral or natural results which was a major anti-climax after the
magic their speaker cables brought to the equation.
