Hey Purk, how does the battery life of the D-515 compare to the D-303?

Expect around 4 to 6 of hours of Alkaline Batt with D-515, while D-303 has around 2.5 to 3 hors. I never tested it myself, but the 2x1800 Mah lasted me around 4 hours on my D-515.

Yeah, I just wanted to know if the d-515 lasted longer then the d-303. I thought it would since it was newer model.

Biggie.

maprik,

Your comments about the Sony D-303's line-out and the Panasonic SL-SW860's "line-out" are right on the money. You see, Sony actually bypasses the crappy headphone-out op-amp in sending the audio signal to their PCDP line-outs (yep, even their newest models are like that). Panasonic, on the other hand, still has to send its analog-audio signal through their PCDPs' cheap headphone-out op-amps before splitting the signal between the "line-out" and the headphone-out.

And because the Panasonic PCDPs have had to pass all analog audio signals through the crappy op-amps anyway, even if you use the "line-out", I think that Panasonic has made a wise decision to eliminate the line-out altogether on their North American-market PCDPs.

BTW, my D-EJ1000 is rated for 41 hours on just the internal NiMH gumstick rechargeable batteries - but for my practical purposes, I get just over half that much. I could reach 41 hours only if I put the D-EJ1000 in the "Repeat Entire Disc" mode, with the volume set no higher than 10/30.

Originally posted by maprik The SONY isn't perfect, however. It's very heavy and bulky. Still portable but twice the weight of the Pana. Also, the DC power jack is right next to the line out jack. With the AC adapter plugged in I can hear an audible buzz. Perhaps I don't have the right adapter but I was told that a 9V 800mA adapter was what I needed. I may have to experiment with that. But with just battery power the SONY is dead quiet and really shines. It's sucks batteries dry so fast though. I'm going to get a couple more AA rechargeables just so I can have 4 pairs to rotate through.

I rigged up a battery pack consisting of eight 3000 mah NiMH "C" cells in series that I hook to the D-303 where the AC adapter would normally go (rated voltage of the batteries in series is 9.6 v: close enough to 9 v to work fine). This gives a longer battery life than the internal battery (BP-2EX), or two AA's in the adapter. The power drain is greater, though, since the D-303 shuts of the optical out and remote control when running on the internal battery. OTOH, I can now use the remote when on battery power if I want to. I haven't actually figured out the actual run time on the external pack yet- I just made it up this week. I really dislike the noise from the AC adapter, so this was my way of getting rid of it and running for longer than 2-3 hours at a time.

Very cool. How can I rig up something like that? You just hook up 8 batteries in series and plug it in?

If running alkalines, use six. They're rated at 1.5v, so six in series is 9v. If using rechargeables, use eight. They're rated at 1.2 v, so eight gets you to 9.6 v, which should be fine. You could possibly get away with six (7.2v), but that's a bit light. Radio Shack has battery holders, and plugs to fit the player. I use their adapta-plug, so I can switch it out for different players. I've actually got two holders, 4 cells each. For modern players that need 4.5 v, I only use one of the holders. I use clips that allow me to detach the leads, and hook one holder to the adapter, or hook both holders in series to the adapter fro 9 v. The Radio Shack adapta-plugs can be replaced for different players, plugged in either center positive or center negative, so this setup is very flexible.
