Help with a Passive Preamp


Looking for a Passive preamp and have narrowed it down to 3 - 4 candidates. The Truth with remote, Tortuga Audio LDR300x.V3 Passive, Luminous 

Axiom II Passive Preamp Walker Mod with Remote or maybe the JOB Pre-2? It will be down stream from a Mytek Brooklyn and a Linn LP-12 with a Ruby 3h with a Sutherland 20/20. Downstream is a Pass Xa-25. The Tortuga has the advantage of being able to ad a gain module if necessary. 

I have heard the Truth in my system and it was very good. Your thoughts?

I have been intrigued by the Tortuga Audio passives for a long time. I used to run a highly regarded passive line drive (the name escapes me but I still have it) with my McCormack DNA-1, with CDs as the source.

Here is a good AbSound review: https://www.theabsolutesound.com/articles/tortuga-ldr3v2k-passive-preamplifier
I like the sound of this one too, especially since they offer it with both RCA and XLR ins and outs.

LDR3000x.V3 High Performance Preamp

$1,495.00$3,295.00

The LDR3000x.V3 is a flexible high performance, remote controlled, LDR (light dependent resistor) preamp available in 9 different configurations including as a passive, as an active solid state or as an active tube type preamp. Each type can be ordered as single-ended only (3 in | 2 out | RCA), balanced only (3 in | 2 out | XLR) or mixed RCA/XLR (6 in | 4 out). Each configuration can be remote controlled (Apple remote) or controlled from the front panel (rotary encoder) with a high contrast, white-on-black, interactive menu driven OLED display.


I have an Axiom II with Walker mods and use it occasionally. 

I like the clear presentation that it makes, which reminds me of how I think Audio Research preamps sound to me.

But after a while I find it a bit fatiguing in my system. I reinsert my CJ 17LS2 to obtain the texture and nuance it provides to my setup.

Thanks for listening,

Thanks for your comments!
Given the fact that I had the chance to listen to "The Truth" preamp for several hours in my system, kinda of gave it the upper hand. However, all the units that I mentioned seemed to have good reviews.
I guess my final concern is; does my Sutherland 20/20 have enough gain? I'm not a loud listener.
I have lusted after the TOL XLR Tortuga except that requires a separate dac and the associated ancillaries= $$$$$. I am quite happy with my Audio Alchemy DDP-1 DAC/PRE+ PS 5, both can be found for ~ $1200 used


I had/loved a Hattor dual mono passive when I was using my Oppo 105 direct outs, but had an impedance mismatch with my then class D amps. I could have had the gain module sent to me (~ $400), but I was not willing to play tech

What is the gain on the Sutherland? What is the output of the cartridge that you use? What is the input sensitivity of the power amp? What is the sensitivity of your speakers?  All of these will play a factor if a passive preamp will work in your system!
That should have enough gain. Here is some info about that Truth passive! If you want to play with a passive you should give the Schiit SYS a try for a mere 50 bucks!
