A friend of mine and I recently did a parallel experiment involving a €13'500 R2R DAC with "67-bit FPGA-based digital volume" versus the same DAC in fixed output mode running into Lio as AVC passive preamp (just the Slageformers, no tubes). His speakers are 104dB efficient, mine were 85dB, i.e. a huge difference in how much signal cut/attenuation was required. In his space, adding Lio and one more interconnect was decisively better than running DAC direct. In my setup using 12dB of cut (the DAC maxes out at 1.4V out), digital volume vs. Lio was pretty much a wash but using higher attenuation, Lio was better. A reasonable conclusion to be drawn from that is that, a/ Lio as autoformer passive is bloody transparent aka invisible and b/ that outside an even very high-resolution digital control's non-lossy window of attenuation, Lio's volume control either is superior per se; or c/ that its drive of longer cables becomes superior to a digital VC as more attenuation is engaged. Hopefully this is useful to some who consider Lio as a purist preamp with comprehensive remote control
I am also trying the lio with my totaldac twelve vs direct , AVC/Tubstage upgrade . My current preamp is very transparent also but has no remote option .
TomS's testament is strongly persuasive given his past system(s) and acute understanding of the advantages of S-I-M-P-L-I-C-I-T-Y Best,Anand.
I have been using my Lio I'm guessing close to 2 weeks now , today I put back my original Preamp and to honest I'm having a hard time deciding which way to go . The things I do like about the Lio is it does have a bit better detail and vocals are clearer , I also like the option to add modules if needed . I did get the HP module but my modded Woo Audio WA22 HP amp does out perform this module . I'm not saying the Lio module does a bad job because that's not the case . I was very happy with the lio HP module until today when I went back to the Woo . Again we are talking 5x the cost with mods and tubes . I'm going to listen another week to my old preamp and then switch back to the lio and decide .I also have some new speakers coming in the next week sensitivity 99db Id love to try the lio module with but I dont know if I would have enough time . My current speakers are around 84db Joseph Audio Perspectives and require a bit more power .
Hi ddark65Unfortunately you didn't list your LIO's configuration so I have a few questions.1. Do you have AVC/Tubestage module in your unit? Since you have so high end Woo tube amp I will assume the answer is Yes. Based on that my next question is do you use stock JJ tubes? If answer is Yes try some other tubes, which will cost you way less than tubes for the Woo, before you decide which way to go2. Which headphones do you use? Having experience with tube amp you should know well that you need to make sure you have tubes which are good match for your headphones for each amp to make fair comparisonOleg
