marantz 11s2 sacd player modifications


has anyone had a marantz 11s2, 7s1 or other older marantz reference sacd player modified ? if so, how did the sound change ?

i will be getting a marantz 11s2 soon and am thinking about having a tube buffer stage installed, to "warm up" the sound. i am not aware of anyone who does this.

does anyone know of any modifiers who have done this in the past ?

thanks

As a SA11-S2 owner, I can add that you will be very disappointed when expecting a tube sound from the SA11-S2. For a tube sound you test the Raysonic of MF's.
Welbourne Labs sells hybrid modules for players. They come with an outboard power supply, which is a very good idea. This way you can use a power cord optimized for the analog stage, and another for the digital. Same for PLCs.
The modules have a tube input, and mosfet output, no coupling capacitors, so they should give a nice full, somewhat more 3D sound.
being a SACD player which processes more digital signal than a CDP, it's important to lower it's jitter error.

I too, had the Underwood Upgrade. Very nice,but even more of an upgrade was the RAM upgrade I got on the same Marantz some years later. Do the Clocking upgrade(the top of the line) and see if you agree. The only thing about the RAM people is they are slow, way slower than they say they'll be. And hard to reach.
