      “I am truly gobsmacked by this preamp.” “The difference it makes to the sound is astonishing. I echo what others have said: clarity, purity, sound stage. But I particularly agree with “clean”. It’s really unbelievably clean. And natural. Very very natural sound. And the one thing that I don’t think others have mentioned but which…

    • LDR3.V25 owner comments

      “There have been many goosebump moments.” “…let me be clear. I love it! First listen after completing assembly was to LPs, with the turntable feeding into the Meitner’s phono section and from the Tape Out (fixed level) jacks into the Tortuga. Sound quality is noticeably better than through the Meitner’s own line stage, top to…

    • LDR3x.V2 preamp board owner comments

      “…I am FLOORED by the sound quality…” “Today I received the LDR3x board and I am FLOORED by the sound quality. I’ve been using a TVC [transformer volume control] for several years and was very happy, but the LDR simply blows it away. I am hearing detail I never knew existed in recordings I have…

    • LDR1.V2 preamp owner comments

      “I have an LDR-1 and it is fabulous. Best preamp I ever owned at any price. When I bought it I thought I would get super transparent sound at the cost of thinning things out. Usually, that is the price for transparency. I took the risk anyway. I was dead wrong. The transparency is indeed…

    • LDR1B.V25 owner comments

      “Truly the best sound I’ve heard in my system.” “What an experience! Truly the best sound I’ve ever heard in my system. A layer of “mush” has disappeared and angry high S’es are now pleasant. More details and less harshness, especially in mid-upper-high range compared to the EC4.6. It is absolutely marvelous at low levels,…

    • LDR1B.V25 customer comments

      “It’s an audio tour-de-force” “I’m rediscovering my entire music collection, and have been reduced to tears by things I thought I knew.”

    • LDRx customer comments

      “….hands down the best preamp I’ve used.” “Open, easy, organic, transparent etc., and – above all else – natural. It makes other preamps (esp. active ones) sound electronic and mechanical.”

    • LDRxB customer comments

      “Yes, it’s that good…” “I can honestly say though even at $2695 this unit will easily blow away stuff that is 3x the cost. Actually, come to think of it, I’m not sure what else one could want no matter the cost unless you want fancy aluminum cases and bragging rights.”

    • LDR3.V2 customer comments

      “It blows me away. Easily the best I’ve heard.” “What did the LDR3.V2 do for the sound? To my surprise, a sense of even more transparency. There are details in the midrange and treble that are just more obvious now. The treble seems more extended, but there was absolutely no change in tone. I don’t…

    • LDR3x.V2 customer comments

      “If you must have the absolute best, look no further.” “I have just installed the Tortuga LDR board and can say that it is the be all end all of volume controls. It is dead silent and any level changes are seamless and silky smooth. I believe the vision of the Melos circuit of the…
