Pass Labs “House Sound” vs. McIntosh “House Sound”


I’m contemplating swapping out my McIntosh C2500 for a Pass Labs XP-20.  I’ve searched the forums for posts on the Pass Labs XP-20, being that it was released quite some time ago, I didn’t find too much referencing the sound characteristics.  Read plenty of reviews, but those, as we all know, are often full of audio journalistic color.  Any one able to comment on the Pass Labs “house sound”, per se?  Possibly what trade offs happen when migrating from McIntosh preamps.

Why not just use the DEQX as the pre and do without another component in the chain?
All, thank you for the comments.

@stereo5 That question cuts deep!  I do like the C2500, 85% of the time.  On most of the music I listen to, it is a pretty full sound, so to speak.  I often wondered if I was missing out on some lower end energy and details in other ranges.

I do have a REL sub, which is blended quite well into the overall presentation/soundstage, but I often think I’m missing some 200hz and below or it’s getting sucked out of the source material.  I’ve sent the room response curves off to GIK, which they provided room analysis on a different room and recommendations for treatment.  I used the same panels, in the same locations.  GIK didn’t identify anything that could be treated, as the room responded ideally to the current panel setup.  

I’ve made adjustments to the DEQX, with a little bit of success.  In all, actually, there’s nothing wrong with the C2500 and I have nothing but positives to share regarding it.  If anything, it’s me tricking myself into believing I’m missing something.  That, and like many in this industry as a hobbyist, we like to fiddle, tinker and experience our music in new ways.  

From a listening perspective, I’ve always gravitated towards less colorization, give it to me as it was recorded.  I prefer to hear all the details.

 I did pull the C2500 out of the chain, along with my Direct Stream Jr.  The DEQX DAC, not bad at all, but it’s a little too digital sounding, to my ears.  I also believe I failed to mention I use the DSJ as my DAC.  I also got out of the vinyl game about a year ago, so I have no requirement for a phono stage.

Hi Todd,

If I understand correctly the chain you are using is:

Digital Source >> DEQX >> DSJ >> C2500 >> BHK300 monoblocks >> Speakers

Is that correct? 

Also, I'm wondering where and how the REL R-528SE sub is connected.  Specifically, if you are connecting it at speaker level what is the black wire in the Speakon cable connected to, which can be an issue given both that the amps are monoblocks and I believe also have differentially balanced outputs?  And if you are connecting the sub at line-level, given that the sub only provides a line-level input for one channel how are the two channels being summed together?

Also, regarding the experiment you conducted with the C2500 and the DSJ removed from the chain, findings that were reported to me privately by one of the other members who participated in the "Is DEQX A Game-Changer" thread, who like you used a Premate, suggest to me the possibility that the Premate's unbalanced analog outputs **might** be sonically superior to its balanced analog outputs.  So assuming (as appears likely) that your experiment was conducted using the Premate's balanced outputs it might be worthwhile repeating it using the unbalanced outputs. 

Best regards,

@almarg Thanks Al!  That’s a great thread.  Correct in my signal chain.  I’ll swap out to RCA’s, see if that alters.  I do believe I may be approaching the point where an additional sub will have to be deployed, right now I just have 1.  

I’m using the RCA sub preout into the REL.  Interestingly, REL is imparting their filtering philosophy across all inputs, which made it a bit of a challenge to tame it with the DEQX.  There’s a massive spike at 50hz, stretching about 6db down to 30hz and 6db down to 80hz, which revealed itself when Larry/DEQXpert was comparing phasing and room measurements.  In light of this, I’ve been debating on replacing the REL as well.  

I would strongly suggest you consider the PS Audio BHK Sig preamp, too.  You run the 300 mono's and the DSJ DAC, so you know their equipment delivers.  I really like that preamp with my 300 mono's.  It sure is worth a try, and a demo wouldn't be too hard to come by.
