It is the second time that I have visited this cryogenic specialist. The first time I took over 200kg with me. This week I brought nearly 120kg to Germany. The official price is now 35€ per kg (as with everything on this planet the price has gone up lately). But I pay the specialist somewhat less than this official price due to my large and heavy ‘shipments’. For this price the audio items get an intensive cryogenic treatment of about 24 hours.
Last Sunday I picked up my audio components (of in total nearly 120 kg) in Germany after their cryogenic treatment: the cryogenic process of the first batch lasted 24 hours while the second batch (with more and heavier pieces) received a cryogenic treatment of 26-27 hours.
After my journey to and from Germany (all in all around 6 hours of driving) I added the first part of these newly treated items to the Tidal Audio LA system on Sunday and the second part yesterday.
So what did this combination of adding 18 new pure copper slabs and the cryogenic treatment of various audio components yield as final sonic result? Well, yesterday I particularly experimented with mass loading my Wadax reference server and Wadax reference dac and the results varied with (i) inserting more pure copper slabs and (ii) removing these pieces.
All in all the sonic differences for the better are very interesting and really profound: actually the sonic end results exceed my expectations and learned me - again - that are audio components are prone to so much more distorsion than we think (or at least what I thought initially). And - but that is not new of course - solid mechanical isolation is utterly important.
As was to be expected I experience better dynamics, more command and not only a deeper but also a more articulate bass / low end. The dynamics I am able to achieve with a tube amplifier of ‘only’ 20 (push pull) watts in combination with my Tidal Audio LA’s are stunning.
In addition the sound is more open than ever before while the various musicians / instruments are also better separated in space than I have ever heard in my life. Furthermore the music presentation has become more (i) transparent and (ii) fluid with added (iii) refinement, (iv) smoothness, (v) focussing and (vi) serinity. And due to the deeper and more articulate bass / low end the midrange has become fuller.
All this implies a big (sonic) leap forward. There remains only one area that in my view can and also needs to be bettered: the rendering of the high frequencies, that is I would like to experience somewhat more ‘fullness’ on top. But I know how this can be achieved: the high frequencies will be addressed in step 2 and step 3 of the final phase of optimizing my Tidal Audio LA system.
So yes, adding 18 additional pure copper slabs to my audio set up and cryoying quite a number of my audio components was a big sonic step forward. This was the first step in the last phase of upgrading the Tidal LA system.
In the second step I will add four of Tripoint Audio’s new signal filters. These filters can be ordered in two versions: a silver and a gold signal filter. Although I have not yet heard them ‘live’ I did experience a few a/b comparisons over the phone. The gold version sounded ‘fuller’ and more transparent than the silver version with - inter alia - more (i) command and (ii) serinity. So I opted for four gold signal filters.
Two of these new gold signal filters will be connected to my Tidal LA loudspeakers while the other two filters are ‘reserved’ for my Kondo g-1000i linestage and the Wadax reference dac (the main unit). To maximise their performance Miguel will built two new grounding cables for the Tidal LA’s as well as a short cable for the Wadax reference dac.
I will try to combine the gold signal filter for my preamp with one of the three Tripoint Audio’s statement grounding cables I am currently using.
Not sure yet when all these items will be ready but the delivery will take at least one month.
