I'm using a Sony PCM M-1 and a pair of DPA 4035.
I use a homemade batterybox for 48Volt.
I wonder if I should get me a microphone preamp....
Any suggestions anyone ??

Do yourself a huge favor-dump the DAT and enter the 21st century.
Get yourself a good all in one box like a Marantz PMD-661 or possibly a Fostex FR2-LE (not one of my personal favorites, but most owners swear by them).
Or get a preamp like a MixPre, Tinybox or used Littlebox and a small recorder like an M10.
For loud stuff it may not sound audibly better than your DAT set up, but you'll be amazed how much more convenient it will be to use. Plus you'll have more clean gain for quieter stuff (especially with the preamp-M10 system).

Are the levels you are getting insufficient with what you have? That's the main reason to get a preamp.
The most compact 48V pre is the tinybox; it's also the least expensive (good) one. After that, at a large (nearly 4x) step up in price, and call it 2.5x larger in size, is the Aerco MP-2. I love mine, and I prefer the sound of it over the tinybox (which I should, given the larger components the Aerco's larger case can hold). The Aerco also can run at least 7hrs off of an internal rechargeable battery, which is key. Tinybox, even longer.
There are also the Sound Devices small pres like the MixPre and MP-2, but IIRC they won't last terribly long on battery power, maybe only a couple of hrs.

Doesn't anybody bother to test run time? I just did. Got 5.5 hours before the 'low battery' light started flashing on Mixpre-D running 2 P48 mics and Sony 7506 headphone.
Running 2 Powerex 2700 NiHd batteries. I'd call that really efficient.

^^ I have, but it has been awhile. I have an original, later model MixPre (not -D) and did a rundown test using fresh Duracell AA's with a pair of AKG 414 XLS's using full 48v phantom. Got to about 2 hours, 10 minutes and then the power dropped off rapidly; like within a minute or two it was unusable. Don't have their specs handy but the 414's are LD's and I believe fall fairly close to the middle in terms of current draw (~5 mA; max supported for phantom is ~10mA). Expect to get longer times from more efficient mics and shorter with less efficient mics, and longer times in general if you don't use full 48v. Don't know for sure, but Sound Devices may have also tweaked the -D version to get longer runtimes from the batteries. YMMV.

I would assume that since the OP is running Omni's that stealth is probably in the equation.
I would also assume since the OP is running $4000 worth of mics that spending another $500 isn't a problem...
I would second the Tinybox > M10 option. It's small, and will sound pretty good. Also the M10 has INSANELY good battery life. The Tinybox isn't too shabby either, but I'm not running it at P48V. I would assume battery life is a little shorter with 48V vs. the 16V I'm running.
I think the biggest plus is the ability to run 24 bit, so you can run your levels a little lower and boost them in post. Very handy when it's not a good idea to keep checking your levels.
DPA 4035 > Tinybox > M10 is a pretty sick little rig.

Thanks. Mics drawing 2.3 mA per channel. Also tested 8xAA battery holder with 2700 Powerex batteries. Ran 14 hours before shutting down. I'm happy with the MixPre-D.

I would go the preamp>M10 route. I sold off my MBHOs AND 722 just to run mk41>sax>m10, and I now run 2 different rigs, both of which run mics>preamp>m10. I cannot say enough great things about the M10. Its small as all hell, gets amazing battery life, and IMO, has a KILLER ADC/Recorder section :)
So I would say go the TinyBox>M10 route and you will NEVER LOOK BACK ;)

Delivery on the Tinybox was up to around 6 weeks. FYI. I don't think you should let that influence your decision, it is worth the wait.
