Line Stage Preamps that blew you away $2500 Edition

Used Audio Research LS-25 MKII, bought several years ago for $2500. Last one I need to buy.

I had an Allnic L-4000, dead quiet, holographic, great  low end.

I too do not like transformer coupled passives. I have been using the Luminous Audio Axiom passive unit ( his very top of the line ) now for 4 years or so. I was into passive years ago with products from P.S.Audio, Mod Squad, and many others. For whatever reason, I felt these lacked something. I owned 2 hi end preamps ( at the time 6K ea. at retail, 1 tube and1 ss ). I also have a few RGR preamps, Hitachi ( do not laugh ), Soundcraftsmen, Hafler, Yammi, Citation, AGI, and maybe a few others ( some modified, all heavily chassis damped ), all working great. But, no cigar. I do not hear my Luminous in the system. The internal chassis is damped with Dynamat ( every preamp / passive known to man, can use some internal damping ). I damp everything.......tuning the component is involved. My dac feeds into the Luminous,single ended, and it works out great with whatever amplifier I choose to listen to from my collection. Short, simple signal path; great parts; Khosmo system; extremely well damped; nice readout; did I mention, I do not hear it. I do not hear it. If this is what you want and if it works for you ( contact them, he impedance matches to your gear ( and can change it at a later date for a small fee ) to match to a new amp ). Highly recommended. Great people. Enjoy !

@mrdecibel interesting. I don’t claim to be technically proficient but I’m curious as to what it was about the transformer coupled designs you didn’t like.

as for “do I want a passive” the answer is I dont know. I, personally don’t care about fidelity and neutrality as much as musicality and “it just sounds good to me”. My attraction to tubes is that I can color the sound to how I like it, but the b*tch about tubes is that they aren’t cheap and wear out.

I mentioned Hattor upstream as it had both passive and active stages. The active stages had low gain (I have way too much) and I thought that being able to remove the attenuators would be a good thing.

I have a couple of Transformer based passives, they are not all created equal. I just had one custom made for me that is minimal in design and function. I also have stepped attenuation based on ladder resistors. 
My amp has low gain, only 11.5 db of gain, so I needed to preserve the input signal as well as I could. I am using balanced inputs to the passive, the transformers match the impedance loads on both ends , so they are less sensitive to cables and impedance specs. The balanced voltage is higher and maintained in this passive even though I am outputting to single ended. so I don’t lose any drive with the transformers like I would with resistors or an autoformer.  The clarity , noiseless background and dynamics are all excellent. I’m not missing anything. It simply lets the music through without any altering of sound. Transformers turn voltage into current at attenuation instead of heat, so low levels sound more full..  I’m a minimalist and a firm believer in less is more , keeping it simple when it comes to the signal path..  

My previous setup was more conventional and more expensive with an active pre Alone was $10k..  I seem to enjoy music more with less spent and less mucking with the signal.
