New Tortuga passive/active tube pre looks like a winner

I will be keeping an eye on this one when it’s released later this month. The ability to run pretty much any amp on high efficient speakers with the flavor of tubes sounds tempting. Should I assume both outputs ( xlr/rca) are active at the same time to feed a subwoofer as well as a amp?
This Tortuga might be perfect for you, as you seem to like tubes, but this is not a 100 % passive pre, imo. The attachment above, to the piece, even indicates, in the 1st paragraph of the description, it is an active tube preamp.
Yes, an active preamp for sure, but some mistake zero gain for “passive.”  Plus, the seller manufactures “passive” LDR attenuators so there may be some inclination to assume the pre is passive since there is no gain.
it seems they have combined their tube buffer (an active, zero gain, buffer) with their LDR attenuator.
You can also order it with +6dB of gain, which may lead some to believe the version without gain is a passive (it is not).
All that said, there is nothing wrong with not going the passive route and in every instance I have tried, I preferred a zero gain buffer or low gain preamp to a true “passive” attenuator or auto-former set-up.
Hey Guys,

I'm trying to setup a review for Six on Morten's new design.  It looks based on an innovative design and it's price point that it should be very interesting, indeed.
Curious, what about it do you believe to be "innovative?"

Hi All,

Thought I'd pipe in here with some perspective. The LDR3000T is indeed NOT a passive preamp although it does employ our V25 LDR preamp controller/attenuator which is the heart of our current line of passive preamps. Downstream there's a zero-low gain active linestage with a tube input/gain (voltage amplifier) stage followed by a discrete solid state JFET buffer (current amplifier) output stage. We run the tube deliberately zero to low (+6 dB) gain running at a slack plate voltage of only 42 volts. The input stage is direct coupled (no cap) but the output stage does employ a DC blocking output coupling cap. By keeping the plate voltage low we can use the same voltage to run the class A buffer output stage. Some or all of the above tends to illicit cries of heresy and blasphemer from certain orthodox tubies. The active linestage is a second generation derivative of a similar circuit used for the past 2 years in our TBP.V1 Tube Preamp Buffer which has been very well received by our customers. heresy notwithstanding. I make no claims about this design being purely original first-of-kind work but the devil is truly in the details. The overall synergy produces a remarkably pleasing sound that I personally find very enjoyable and satisfying. We think other folks will as well.

Thanks for info. Everyone will be looking forward to hearing the unit and reading reviews.
