Man, this has gotten interesting. This headphone amp has an output to be used as a pre-amp. I ignored it until I was done with my tinkering with the power supply, resulting in what I preferred for a headphone amp. So, last night, I added some RCA connectors to the output, and hooked it up yo Rachael. The good news is that I am listening mostly to the pre-amp, and it's differences through my system. I like this because, I already know what Rachael sounds like, and have a bit less to process in the evaluation. Here is the interesting part. There is a midrange presence that is added which I really like. It doesn't make sense because part of that is what I am trying to tame about my speakers. It does add quite a bit to the presence of the hall. But Wait A Tick, something is quite different here. There is too much 'hall effect' that wasn't present before on my Lyle Lovett CD. THEN it dawns on me. The hall effect may very well be the microphonic aspect of these tubes! MAkes sense. CD plays music through system, speakers make sound, sound hits tubes causing the 'microphone' to be excited, microphone sends signal back through system... you get the idea. Kind of like owning an amp with a delay, almost echo. I will try this at lower volume today, and set the pre-amp away from the front of the speakers. Coll, but not cool, ya' know?
