Tube preamp recommendations $3K-$7K range


I am considering replacing my solid state preamp with a tube pre. I plan keep my solid state amp. Also, my DAC/PSU are tubed. Am looking in the $3K-$7K range. Based on reviews and audio forums, I have narrowed my search to the three units below:

PrimaLuna DiaLogue Premium
Backert labs Rhythm or Rhumba Extreme
Modwright LS 36.5

A bit of background: I purchased my Haflers in the mid '80's (!) to replace my venerable Marantz college dorm unit (along with Polk SDA2's to replace no-name bookshelf units an audiophile uncle bequeathed to me. I vividly recall his aquamarine glowing McIntosh amp, Thorens turntable and Thiel floor standers that were as tall as I was at the time...)

The dealer had modded the Haflers by Musical Concepts, which was my first exposure to John Hillig's work.

Last year I invested in Musical Concepts' most recent Hafler upgrades for my amp, preamp and cdp. Not much is written online about John's mods, but to my ear the improvement was astounding in every way my ear could measure. Since that time, I've continued on the upgrade path to my current system with which I am very happy.

Yet, I am curious about what tubes will do to my system. My current system (with which I am very satisfied) is:

Hafler DH 220 Amp/Musical Concepts PA6 Elite Ultra Mod
Hafler DH 110 Preamp/ Musical Concepts LXII Elite Mod
Musical Concepts modded Rotel 1072 CDP//Musical Concepts Elite Mod
Modwright tube modded Oppo Sonica DAC with Modwright external tube PSU

Harbeth m30.1 monitors
Dual HSU VTF1 MK3 subs
DSpeaker Anti-Mode 8033-S

Fidelizer Nimitra Computer Audio Server as Roon core
Fidelizer Nikola LPS

Goertz BP 1000 VA Balanced Power Conditioner
Furutech e-TP60 Power Distribution Unit

After market ICs/PCs:
Wywires Silver Juice II PCs and Modwright Umbilical
Shyunyata Venom 14 PC
Synergistic Research Element Tungsten and Accelerator ICs and PCs with Michael Spallone V2 modded MPCs

Listening room for near field listening is 12x10x8; opens to larger living area where I do much listening as well.

I welcome any input or recommendations you may have.

Jaybe & Randy-11 - I've read numerous threads stating ARC gear sounds it's best in balanced configuration (requiring XLR interconnects).  Is this true?  If so, that would be good for the original poster to know.

I too have heard good things about Don Sach's preamps.  I've yet to hear one, but I'm intrigued with his use of 6SN7 tubes which allows one to tweak the sound with tube rolling.  They also have a retro/vintage look that is cool.

I've been using Aesthetix Calypso preamps for probably 6 years... initially with the base Calypso and now with the Signature version Calypso.   Best preamp I've used in my 17 years as an audiophile.  Responds well when fed a diet of high quality NOS tubes and very reliable in my experience.   The base version can be had used for around $2,500 (allow $600 for some premium NOS tubes) and the Signature version is harder to find used, but can be had for around $3,600 if you are patient.

I would hope the ARC Ref 5SE is better than the Calypso at more the double the retail selling price.

How does it sound running single ended?   I've heard that ARC gear sounds far better in balanced mode, which has kept me from trying their  preamps, as I'd have to buy new XLR interconnects and both of my tube amps are single ended only.
