Anybody Felt Lower-End ARC preamps Bass-Shy?


Any folks here who upgraded their lower-range Audio Research preamps to better ones and noticed a considerable improvement in the bass department? I own the LS-16 and thought the bass doesn't go to deep. Will the LS25 or LS26 have much better bass compared to the LS-16?

Thanks in advance.

I had an LS15 and bass was not one of its strengths. It was replaced by a VAC Renaissance which does do bass with impact but of course there is a substantail price difference too. I would guess the more expensive ARC preamps would offer more bass.
I owned an LS-25 mk1 (6922tubes) Infinicaps for many years. While the bass went fairly low, rhythmic drive/impact was sorely lacking.
Ryder, with so many variables in the system, amp, preamp, cd player, cables, subwoofer, settings, placement, recordings, it is tough to have any idea if you have a lack of bass and if so, where it might be coming from.

One thing I have discovered with some of my customers is the importance of finding out if they experience a lack of bass all the time or just with some recordings.

What music/recordings do you listen to? Is the bass great with some and not with others, or does it feel light weight all of the time? That might help to shed light on what you are experiencing.

In relation to what other tube preamp?
I have had the LS-16 in my system and the bass response was rather poor in the upper registers.
