Visited DCC yesterday. This was also my first audio visit outside the UK since the pandemic began.
Since my last visit, he has replaced his SME V on the Brinkmann Balance with SAT, added Stacore rack, platforms, and footers, Thrax preamp that he is using to biamp with Tenor hybrids on mids and high of his Dappolito Focal Acoustic, Krell on the bass (previously I had heard Krell across the range), and he has treated his room with SMT panels.
I cannot say what each component does in isolation, but overall the collective sum is that the system is much more coherent, and not having room interference which was pretty high on my last visit. It is no just a coherent system with high linearity into deep bass.
The one thing that I could compare was with and without Consolidated Audio, and the difference is night and day. With the SUT, the system just breathes more, there is more oomph, better tone, better energy, better stage, and extension on both sides. The nuances are higher as you can see each note more amplified, like the system is finally being driven properly. It is lifeless and flat in comparison if you take out the SUT. Keep in mind his Allnic phono MC has a SUT, and his Transfiguration cart is 0.2 output which is very low, so the SUT is built to match the cartridge. Might make a case to not upgrade your phono but add a good SUT to the mm first.
With the addition of the SUT and the SAT, the TT set up is much closer to his Studer A80 then I remember. The Studer still has more body, tone, dynamics, and impact, but I could go back to the TT set up and listen without missing anything. He also had a Nagra IVS in the same system, and the brief compare we did, while the Studer had more bass extension, body, and tonal nuance than the Nagra, if I had to pick one, I would pick the cheaper and spend the rest on tapes.
DCC and another guy (who is a passive reader of the forum living in Paris), are in many ways like montesquieu. They have deep knowledge of classical music, and I always thought of them as guys who could live with simple TD 124 type set ups into small Tannoys and with lots of tapes and LPs rather than big systems. For them, the music matters most. Now while dcc does have some phenomenal gear in his main system, he did have 2 small systems in the bedroom, both with TD 124, and one of them with LM 805 and cube audio nenuphar. Having heard the Cube audio recently with first watt amps and also with an entire Aries Cerat system, I was most impressed with DCC's. Whether that it is due to the analog or the simplicity of the LM 805 or both, I cannot say.
What was interesting was that the Hanze hifi TD 124 with SME V and Phasemation EA 200 held its own compared to the Artisan Fidelity TD 124 with Schroder CB9 and Lyra Etna. The AF set up was better, with more nuance and ease of change in dynamic contrast, but these are more Lyra traits imo. DCC could confirm that if he swapped the arms and carts between the two. I think both TD 124s will be at a similar level.
The key takeaway I could identify was the SUT, but Denis can definitely add more color to the impact of each component, as not everyone will be in a position to splurge on all the tweaks.
I thought I would add this here as I wanted to draw attention to the SUT. Whether it be consolidated audio, Slagle (which I haven't heard yet), or whatever you have access to, start investigating by getting the one that suits your cart and use it with your mm input into your phono. I have also had a positive experience with the Ear SUT into Aesthetix IO Eclipse but the delta here was much more significant
