Has anyone heard the modified TRL/Sony DVP-NS900V

Doesn't matter. Play whatever you want.
Unless I am mistaken the break in length is more on the analog output stage, power supply, and the hardwire parts so either format is fine.
I would simply fill up the changer with both and set on repeat.
The player is programmed to stop after so many repeats of all the discs if I recall, so you have to restart it.

Very very nice player and great value.
Make sure you are using a decent power cord with it.

Has anyone recently received the battery powered version of this mod and what are your impressions? Bob

Mine should be shipped this week. There have been a couple of new developments with the battery power modification over the last few weeks. I would suggest you speak to TRL to get accurate details. From my understanding the changes have a very positive impact on the player.

I talked at length with TRL today about the revised full mod with battery power option. I have the basic mod on this unit and it is an extremely enjoyable player as it is.
I am going to try and make a trip to Chicago to hear the full mod with the battery option in a couple weeks. They feel it makes this player quite special. (All modders say this of course), but for Paul to be this excited with his 30+ years of experience is a telling sign.

Will post something if I do hear the full battery mod.

Clio09,
Let us know your thoughts when you receive the TRL Sony. Bob
