Anyone heard Underwood level1 3910 mod?

I would love to hear from somebody that has actually sent in their 3910 and was familiar with the "before" so that they could compare the "after."

I was thinking about getting the "Ultimate" but before I jump in and spend $2700 to tweak my existing 3910 I wanted to ask around a little.

Thoughts?

I can't speak to the Mods, but I've bought several pieces of equipment from Wally and can vouch for him as a great guy to deal with. Also, check out Six Moons.com, I think they have a number of reviews of Wally's modded products.

La45, yes, HRAM indeed uses APL Master Clock.

I am currently evaluating the 3910 mod. I purchased the Ultimate and sent Parts Connexion my 3910. I have finally let the unit burn in for 200 hours as Wally recommended. So far I am disappointed. The upper bass is overly pronounced and the overall sound isn't open. Vocals never come alive - low level detail seems obscured maybe because of the overly warm upper bass. I am AB-ing the unit with a Benchmark DAC-1. I will say that I don't remember the Benchmark sounding as good as it does now. The mod replaces the clock which Wally claims improves the digital out. I believe that has made a large difference. I have ordered some NOS Mullard 6922 tubes which I'm going to try in the unit next week.

Just a suggestion...
I have a APL 3910.
Perhaps your modded 3910 requires a different interconnect and power cord .
Try a silver interconnect like AZ, Kimber Select,Ridgestreet Audio, Purist Dominus, etc.
It may tighten the bass and open the sound.
The Purist Dominus power cord is awesome with my APL 3910.
