Mono Powerbases arrive....
Mono Powerbases arrived last Saturday. originally I had only one powerbase which is the standard configuration for the Select II. an option is to have 2 separate powerbase boxes, one for the digital circuits and one for the analog circuits. I ordered this earlier in the month, they built the additional power base complete, and the built the circuits for the second one, then when that was ready I shipped my standard powerbase to the factory and they installed those new circuits and I got it back 3 days later. the only gotcha to the quick turnaround was the freight for 70 pounds to the factory and 140 pounds back both overnight. ouch!!!
but oh, the sound I'm hearing!!!
that morning I had taken my Adona rack apart to investigate whether I could somehow have a separate shelf for each power supply, which is ideal. but I just don't have the height to do that considering my Herzan and dart preamp. but having the tt off and top shelf removed it was easy to just lower the heavy power supplies onto the shelf instead of trying to slip those into the tight space. but it did take awhile to reassemble the system before I could listen.
so there are a few different things I'm doing in terms of set up compared to how it was with only one power supply. before I had the second power supply under the dac and stacked on top of the Herzan and dart pre with a Symposium Svelte Shelf between the pre and the power supply. now it's just the Select II dac atop the Herzan/dart pre/Symposium/BDR cones. then on the upper Adona shelf I have -6- A10 U8 decoupling footers (due to 90 pound total for the 2 powerbases) under the bottom powerbase, then the upper powerbase uses the stock rubber footers into the recesses in the bottom powerbase. I've jumped the top powerbase to the bottom one for grounding, both then to the Tara GME w/HFX IC's and the Tripoint Troy Sig for chassis, and the Entreq grounded to the RCA inputs on the dac.
my opinion is that part of what I'm hearing is improved decoupling performance with both the dac and powerbases.
and I get into all that system set-up stuff because I was absolutely stunned by what I'd been hearing from the addition of the Mono Powerbases. and trying to wrap my head around it I have a hard time thinking it's all the power supplies. my sense is that while the new dual powerbases get most of the credit, it's likely not that simple. we are operating at such a high level of information that everything matters.
what was i hearing? this is a quantum leap. I'm going to avoid the whole vinyl question for now as I have to be careful until I actually A/B recordings, but I do think I'm now at a spot where it makes sense to do that.
that out of the way, I'd say this step up is much more wide ranging in it's implications than I ever would have expected. besides clearly (not subtly) better everywhere, I'd say 'commanding'.....'authoritative'....'grounded/sure-footed'......'bigger/bolder'. before I might say that some tubed dacs have more bloom and in some ways more tonal density. not anymore. the dual powerbases simply take things to a different dimension of performance in my system. listening to familiar tracks there is much more texture and micro-dynamics. the word real and life-like hit me everywhere. the amount of projected musical energy is just in a whole different place from any digital
I have heard. the music floats above yet is grounded in power. super holographic.
the bass is better in every way, more articulation and texture, more tonally rich, goes deeper and with more slam and weight. the nuance and delicacy is a few degrees better which results in clearly more ease and flow. on every familiar recording there are passages where my previous reference is now revealed to have had distortion, and now it's removed. this part really blows my mind.
the noise floor is lower, I'm hearing so much more ambience and sense of dimensionality and feelings of openness and a direct connection to the event, and so much delicate life like detail and the feeling the air is alive.
I will try my best to list some recordings and get into details about them. that is not an easy thing for me, but I will do my best.
