OB, you have asked me a question 2 different times and for various reasons i had not yet answered you.....my apologies.
i was fortunate that yesterday i again took possesion of the pre-production darTZeel preamp......i drove to Portland and back.....got home at about 7:30pm last night.....plugged it in......and listened until about 3 in the morning. for the first few hours digital, then vinyl until i couldn't keep my eyes open any longer. i got my second wind at about 10;30pm and my third wind about 1:30am.
so my aurial memory is now 'real-time'.
so what the hell do i mean by 'liquidity, palpability, and delicacy' when describing this preamp?
when i say 'this preamp' i mean the pre-production dart pre, the pair of Stereo dart NHB-108 amps, and the BNC cables connecting them. since i can only use the proprietary connection at this time i cannot assign cause and effect between the pre, the amps and the cables.
by 'liquidity' i mean 'liquid' as opposed to 'dry'. real life has a lack of edge; if you close your eyes and concentrate on real life sounds (not reproduced) there is no real edge to sounds, even fingernails on a blackboard have no 'outline' or abrupt starting point. real sounds are not 'dry' and lifeless. real sounds are rendered in a context of 'air' around them; they exist in relation to what else is happening.
an SET amp typically sounds 'liquid'......althought usually at the expense of immediacy and lack of frequency extention and speed. the tube warmth of a typical SET amp does portray a type of liquidity, or lack of 'dryness'. the darTzeel combo's liquidity is more a removal of distortion than an added something. my interpreation of what i hear from the dart pre is that a layer of 'hash' or distortion is removed from the music that leaves that more real liquidity that more closely resembles real life.
the tangible benefits of this lack of distortion or 'liquidity' is more real detail. this is easiest to hear with massed strngs or choral works; where it is easy to tell what is different. whereas previously, these musical events were percieved as 'those musicians or instruments over there'....now they are percieved as that group of players over there singing/playing together but now each 'voice' has a purpose and message. it greatly enhances the musical gestault and draws me into the music. i am listening to an event and not the playback chain with it's own character.
palpability is the sense of realistic size and shape of things; also of true flavor, texture, and action. is there something real connected to that sound? is dis-belief suspended? is there a sense of natural scale and feeling? can i taste it? feel it? am i there?
is it palpable? is it real?
delicacy is simply the ability to complete tiny things correctly; and not obscure or artifically interpret the tiny but all-important heart of acoustic music. when music is delicate......it moves me.
these three issues are connected; the dart combo does these things at another level or two higher than i have yet heard before. at first it is a little disorienting; since some of your reference recordings have such a different feel. but after relaxing into the music i have found that everything is just more real.
again; i apologise for the delay in my answer; my heart was just not into the beauty of music for a few days.
