3 great tube preamps. Which would you purchase?


I’m currently looking at a used VTL TL-5.5 Series II Stereo Tube Preamplifier
Don Sachs 65N7 Preamp (new), and last but not least LTA Microzotl Preamp - new. 

I like Ike the fact that the VTL has balanced outputs. Which the 65N7 and LTA Microzotl lack. 

My current amp - Bel Canto Ref500s. Has the option of XLR or RCA for input. I like the idea of going all balanced with my set up. 

Its not mandatory to have an all balanced system if one preamp lacks xlr outputs. It’s more of what will work best.  It’s a heavy investment for me. Regardless of which one I will purchase. I like to set it and forget it. Upgrading every couple of years is despised as much as clothing shopping. 

Price is not always indicative of quality. All three mentioned are great contenders imo. All fluctuate a bit in pricing. If anyone could chime in, stating which preamp they might prefer would be greatly appreciated. 

It’s a safe assumption all have their own sound signature. I’m looking to round off the class d sound a bit. It’s not overtly bright. Though I’ve heard the tube sound. I know it will be a game changer in conjunction with my current equipment.  Very curious to know what the communities take would be on this post. 

I have a very basic set up.  
MacBook Pro 
Dynaudio Special 40’s
Bel Canto Ref Link
Bel Canto 3.7 Dac
Bel Canto Ref500s / most recent build. 
interconnects, speaker cable, and power cords are holding up well. 

Turntable preamp to be determined in the future. 

My kind regards,


@goldprintaudio - thank you for your suggestions. I was considering PS and Rogue as well. Great suggestions. 

@jmolsberg - correct. If I can get a good deal. I’d like to try Herron.
I have not been a fan of the Esotar tweeter, to me it was way to bright and forward. However if that is your bag a nice relaxed tube preamp would certainly help. One that I have used and one that no one does not like is the dehavilland UltraVerve.  $2900 retail with volume control right from the manufacture. 
Look at the Supratek pre amps too, get very good reviews and are beautiful to look at.
@goldprintaudio Thanks for the suggestions regarding the Bel Canto amp---would the PS Audio Stellar GS DAC be a good fit as well? I've also heard good reviews about the Bel Canto and Rogue combo. Question: What interconnects work well with this combo? Or the PS Audio/BC combo? Thanks!
I am also on a very narrow path to find the right tube preamplifier for my class D monos from Merrill Audio that I just purchased a couple of months ago. The funny thing is every person I talk to gives a different response or direction to go, but I guess that is part of the journey that makes final result so worthwhile. I have tried to narrow the list down to as few as possible in the 4k used price range, here is what I came up with.

Rogue RP-7
Backert Labs Rhumba Extreme
Zesto Audio Leto 1.5

The RP-7 seems to be the best bang for the buck and most versatile for inputs/outputs functionality. Love the looks of the Zesto Leto 1.5 it is a piece of art, but also the most expensive. I know the Backert Labs Rhumba Extreme works well with the Merrills because the former owner also used one. I also need HT bypass which all of these fine preamps have. Little surprised that nobody has mentioned the Zesto Leto yet or even an Allinic L 1500. Happy hunting.
