Marantz SA-10 arriving Monday!

I got a Marantz SA10 last week, and I only have about 50 hours on it. While it is better in most respects than the Sony XA5400ES and XA9000ES that I also own, it exhibits a brightness that is quite annoying. Many female voices present a brightness/grain that was absent from Sony’s rendering (especially on SACDs). For example, Jacintha’s voice is super smooth, detailed, and beautiful on Sony, but gains a mild yet annoying shrill with the Marantz. Similar findings for Jacqui Naylor, Vanessa Fernandez, Julia Fordham and even Holly Cole. Do you experience anything similar with your player/system?
I do not have anything else bright in my system, from KEF Reference speakers to Luxman C900u and M900u amplification. The effect is a little less pronounced when switching interconnects from AQ Cheetah XLRs to Gabriel Gold Revelations RCAs, but not gone.

I haven't noticed any shrill except for a couple of days the AC was out. I had a Sony XA5400ES 5 years ago and this flat out beats it. Give it another 100 hours and use a good power cord. Try the filters too. Good luck

Thank you for the fast reply! I thought the filters only work for CDs and not for SACDs. I am using a Wolff Carbon PC, so that should not be the issue. However, one other change that I made with the arrival of the SA10 is that I installed an Oyaide WPC-Z mounting frame with carbon plate on the outlet for the dedicated power line. I can only hope that is the source for the brightness. I have to add the Sony back and A/B test, and remove the new outlet frame. I will post the findings.

When I ran a new dedicated line my system was not sounding the best for a while. My players chassis is damped and isolated with brass cones, maple block and rubber cork blocks on the bottom. Maoleshade system. I think that helps

Sorry for the typos. I just woke up.
