Benchmark LA4 vs Linear Audio Tube microZOTL Preamplifier (Level 2)

I have enjoyed my LA4 preamp, but I want to see if a quality tube preamp would be more to my liking. I have ordered a LTA MicroZOTL Level 2 and it should be here in a few weeks.

My current set up:

Acoustat 1+1 with a SPL Crossover and dual Rhythmik F12SE subs

Innuos Pulse paired with an Innuos Phoenix USB

Bricasti M1S2 DAC

Marantz 8003 SACD (rarely used)

Technics SL1500 turntable with AT VM540ML cart upgraded with a RigB body

Pass Labs XA 25 power amp

Upgraded, but not excessive, cable

I have a month to compare the two preamplifiers and decide if I should make the move to the dark side (tubes). Everything I have read suggests the MicroZOTL L2 should improve stage presence, separation, and depth without significant detail loss. I do 95% of my listening through Qobuz and Sense with the rest from vinyl. The SACD player is only used for the occasional SACD not offered as HD through Qobuz.

Prior to settling on the LTA I listened to a used Electrocompaniet EC 4.8 Mk2 (had not settled on trying tubes yet.) (poor detail when compared with LA4 and narrower soundstage).   I also wanted to try a Pass Labs XP 22, but could not find a used one to try at home (also prior to the tube exploration).  I auditioned a used ARC 5SE (decent soundstage, but suppressed high end and the bass was underwhelming). 

I am looking for any guidance or suggestions the Agon community might have for me.

Thanks in advance!

As A said in a previous post. I own 2 LA-4 preamps, Love them, my system is all balanced. Rock and Roll, great electronics (in my opinion, ex: Pass X250.8, Bricasti M1SE) Nice feature, adjustable gain, and I run my 2 SVS Sb4000 subs via a split balanced cable run out of the rear mono stage of the LA-4  Just my $02.

to Thirftyaudio: I am very pleased to hear your so happy with the new tube pre amp. Let me know if you would be so kind, as to further improvements, etc. in sound as it burns in. I have never gone down the tube route. (enough rabbit holes exist)  Was always curious about the tube route though.

Just curious about your dual sub hook up to the MZ. Mine is currently split through a mono balanced choice of the LA-4. Not familiar with the rear layout of the MZ. Thanks, Robert

Thanks so much Ralph. I'm glad you've met with such success in this never ending journey. As I grow older and have many hobbies (time requirements) status quo in the audio arena is not so bad. However, when I hear your system improvements it makes me pause and consider alternatives, thank you, I think!  Robert  Good luck, I'm a little jealous. Robert
