Jerry shipped mine today so hopefully get it Friday.

A bit off topic ... I already got Brownsfan .02 between PS 9.0 and 9.9. Wig, how does PS 9.0 compare to 9.9 in your system? What tubes are you rolling in 9.9?

Knghifi,

Upgrading to the 9.9 is like removing a bed sheet from your speakers, more clarity, wider/deeper sound stage and more palpable imaging; using Sylvania 13EM7s and Philips 5R4GYS rectifier.

Also, replacing the stock fuse with an Audio Horizon premium 1.6a fuse makes a nice improvement in sound quality but experiment with fuse direction.

I found the Phillips 5R4GYS to be a good tube in the 9.9 driving the 5400,but I did not like that tube in the 9.0 driving the HAPZ1ES. I also don't like the 9.9 driving the HAPZ1 regardless of rectifier, although I haven't tried it with the Phillips yet. I need to reevaluate the 9.9 vs 9.0 again. Preliminarily, I preferred the 9.0 to the 9.9 with the 5400 also. Maybe the Sylvania voltage regulators would change my mind, but to me the 9.9 is a very solid state sounding piece. I haven't found image and stage to be anything special.

Both of these power supplies are sensitive to tubes and ac/DC cords. Maybe I don't have the 9.9 dialed in yet.

Brownsfan,

Sylvanias are much better than stock tubes, better dynamics and a quieter tube. In my system the 9.0 sounds two dimensional in comparison to the 9.9.

I'm using a SR Tungsten PC on mine but the AH fuse is amazing...
