Some big changes in my soundscape recently. They aren't 100% complete but I'm close.
I received a nice package from SOtM yesterday.
An sNH-10G with sCLK-EX, Evox cap (that thing is huge!) and silver wire upgrades. The 3 remaining taps from the sCLK-EX now provide clocking from my NUC's system, NIC and (2) HDMI.
Another sCLK-EX with taps used for the tX-USBultra and my server's system, (2) NICs and tX-USBexp was upgraded with the Evox cap.
Jeff Hedback of HD Acoustics conducted an analysis of my listening room where he measured reflections, decay and frequency response. The cost to do this is very reasonable. Jeff did everything remotely, shipping his gear to me. I played some test tones and recorded them with his gear. I had also been talking with Bob Hodas, who has an impressive background. Bob would come on site and this could be a future, but more costly effort.
I gave Jeff measurements of everything in my room along with pictures. He provided a detailed report and took time to explain the results. He then created a design with recommendations for treatments. My room already had wall absorption panels, but I knew they weren't good enough as they didn't go down to 80Hz. So a change to the absorption wall treatments closest to the speakers, some diffusion and absorption on the ceiling and better absorption behind the speakers was recommended.
I have installed Vicoustic Multifuser DC2 panels to the ceiling and added insulation behind the speakers where there is a cavity behind the projector screen. The DC2 panels are light and easy to install. I did paint them so they would blend in more with the ceiling. As the are polystyrene care needs to be taken.
I have GIK 244 traps on order which will be used to the sides, at the first reflection point of the speakers and on the ceiling above the speaker. I will also be installing a 242 trap in the middle of the ceiling which will be surrounded by the Vicoustic DC2 panels.
Our main efforts were to resolve an issue between 100-200Hz. This is where the acoustic treatments should help. Once everything is in place I will re-run the analysis with Jeff.
My Persona 9H speakers have Anthem Room Correction (ARC) built in. ARC only impacts the sound below 500Hz. While I typically don't run DSP on 2 channel, these speakers are a bit unique and what they can do is fantastic. By applying it at the speakers themselves the change will impact analog sound without converting it to digital. This means vinyl can receive DSP while remaining unmodified analog. I can also turn ARC on and off with the push of a button. The difference is stunning. The low end is tamed allowing for a more accurate bass representation while revealing music in other frequencies that would be otherwise masked. I am hearing sounds I couldn't hear before.
This is just another example of the analysis which helps to understand the room's characteristics and apply corrective action.
I will share pictures of the server - NUC - tX-USBultra spaghetti later. Where I just had a little spaghetti before, it's a big bowl of stuff now. I will also share pictures of the room once the treatment is completed in a couple weeks. I also need to let the new SOtM components burn in as well as apply EMI RF shielding to the SMB cables.
