I am not sure that I am at final stage of my ULF wondering. I do like the integration-free problem of my ULF via tube crossover. I am a bit concert that I am injecting now + 9dB at sub 20Hz and do not feel that I have too much bass. I am a bit more concerns that with use of tube crossover I lost “some” thump in lowest bass, particularly at very high volumes.  The softening of the very last pinch at the very low end in no way annoying or even noticeable in most cases but there are some moments where it is necessary. It is like walking in fog – you need some black object to see in order to recognize how dance your fog. Yes, I am taking about the 8 symphony, fourth movement of guess who?

I would like to have that prodigious slam of that drum but at the same time it looks like the amp that can deliver it do not have the harmonic intelligence that I need from ULF. Well, I need to live with my current ULF for a while. Perhaps I need to re-tube my crossover as I do not think anything is left in it to modify…. If perhaps I need a deferent power amp. I am feel sadden that I sold my Lamm M1.1 amps – for high power they delivered very good bass – it would be interesting to try the M1.1 now in my ULF.

Still, I am a bit wondering why I am so attracted to that soft version of ULF.  I wonder how other people would react to it – to the high power ULF channel with, soften by tube crossover. I do not think that audio people generally hear something like this. Tomorrow an audio guy that I know will be arriving in Boston to hear my new playback results. I wonder what will be his reaction to my new ULF implementation.  I wonder become it is different. Pit is this way my ULF is “softer” then the sound the rest of Macondo, this mostly never happens with playbacks and to hear this type of setting a bit strange but interesting. I wonder what will be his reaction and if he will be able to understand of what is going on.

The playback with ULF doe not sound bad but the elective softness of ULF makes the feeling from this sound a bit different. It reminds me walking across a swamp or deep snow. First you spend efforts to pull your legs from swamp but as you get use to then you can walk and do what you do without paying too much efforts to the fact that each of your step is an effort. With my overly soft ULF it is in way the same:  listening,  you need first to get that feeling of that excessive in size but warm and fuzzy ULF. You need then to learn how to ride that ULF, literally how to lie relaxed atop of the bubble of ULF and let the ULF to drift you. Then mind observers that cloud of ULF is not only thing in the room and that there is a lot of more sounds in the room. The cloud of ULF acts as a metaphysical sustained pedal-point above which all the rest music grows. The softness of that pedal-point is key in my mind as the ULF cloud  is not auditable in normal sense. An interesting effect indeed…
