Recommended Preamp for Pass Labs XA30.8 and why


DAC: MSB Analog
Transport: MSB Platinum DATA CD IV
Cables: MIT Shotgun S1.3 Interconnect & Bi-wire speaker cable
Speakers: Esoteric MG-20

Considered Options:

Audio Research LS27
Conrad-Johnson ET3SE
Aesthetix Calypso Signature
PS Audio BHK Signature
Luxman CL-38u 

This is my very first post in the forum.
Since my speakers' balance has clearly been optimized for clarity and detail rather than warmth and richness
according to Stereophile's review, I prefer a tube preamp.
The MIT interconnect comes with adjustable impedance switching, so impedance matching isn't a major concern.
I prefer a smooth, detailed & balanced sound with wide and deep soundstages. 
Any suggestions will be appreciated.
Thank you so very much.

Teajay, the Linear Tube Audio's MicroZOTL does not have balanced inputs outputs, and from what I know, pass amps sound better thru balanced inputs. So your combo of MicroZOTL and XA-60.8 or X250.8 sounded better using RCA inputs than other
pre-amps (including pass XP-20) with these pass amps even using the XLR inputs/outputs? I am trying to get best pre-amp (without spending fortune) for my new coming X-350.8 amp. I would go with XP-20 but it has 2 units and with huge X-350.8 it will take a lot of space that I may not have.

Thanks.


Another consideration- eddiekuo

you must demo a Pass Labs pre-amp for a proper comparison.
Mcintosh C2500 can be had used or NOS
Mcintosh C2600 new

I recently purchased the C2500 NOS and love it. Before deciding, I researched VTL, CJ and AR, new and used. I’ve had it for three weeks now and it responds well to tube rolling and has an internal DAC, which I don’t use or need, plus two nice phono sections, MM and MC. In my system it has a smooth upper end and very good bass. It came with 6 12AX7’s that are ok. I put in two new Gold Lion in the main slots and and Mullards in the MC area, all were reissues.

Good luck
