I purchased the M10. But when I was comparing the differences between the M10 and the D50, I was looking at them as solid-state 2-track recorders, not as microphones. In my mind the M10 was the winner. I saved $200 that went towards more gear in my rig that was better designed and more practical for the situations I was hoping to capture.
The M10's a good ...
no please don't sell your d50, it's such a wonderful recorder!
the zoom might be good (i doubt it but it is possible), but it's not worth it to sell your d50. if you were a freelancer and pay taxes and do investments you've probably already would've paid of the d50.
if i were you i would invest in a clean and simple 2 channel preamp and a good bag. buying ...
I can vouch for JrF: http://hydrophones.blogspot.se/2011/05/c-series-pro-contact-microphones-new.html
I never leave home without them. Using an H4n.
They are used by BBC, which according to me is a good reference.
Jez riley French is an established name in hydrophones and also contact mics, especially for people who find Trance's offering "on the expensive side".
Also see this: Can you suggest a good contact mic for sound design? (average cost of proposal would be much appreciated)
"Head to head" internal mic recording test of Sony M-10 vs. D-50.
I have owned a D-50 for about 8 years, purchased the moment it came out and used about twice a week. I did have a period of non-use but stored it with fresh batteries and did not get the "dead" problem I've read about. I've owned an M-10 for about 2 years and used it occasionally.
Stereo effect is highly dependent on placement of microphones. Even a great microphone can have poor stereo if it is not in the right spot.
If you experiment, you might be surprised.
To me, the great problem with most stereo microphones is the difficulty in going to mono.
MS stereo solves this (I use an ECM-989 or 999).
I haven't used the D50, but I had a M10 and realized what makes the price difference between those.
In terms of circuits, the M10 sounds good/balanced and clean. It (and the Sony range) must be the best sounding and cleanest in portable recorders, until you spend a lot more money.
However, the more important difference is in how the microphones are ...
WingfieldAudio.com has extensive reviews of several handheld sound recorders, including the D50 and the M10. Most interestingly, they have side by side recording sample tests that you can use for comparison.
I have just purchased a D50 as an replacement and upgrade for my broken H4n. I have first considered using a Sound Devices MixPre D as front end going into the digital in of the D50, too. But after some research on the net I have learned that:
a) this would require using a separate box to get the signal from the AES out of the MixPre into the SPDIF in of ...
I've got Marantz and absolutely love it. Optical In takes 2 channels and I use it as much as XLRs, in cases when I need to rip something from web, or as Save as... function with demo software.
D50's microphone would be slightly better I think, but convenience and inter-transferability of SD card storage format makes Marantz a winner straight away (or at ...
the D50 is a fantastic recorder if you can afford to buy it over the H4n, the mics don't sound any better and the noise floor fairly similar with both using XY electret mics which always exhibit noise, the D50 is a tad quieter but I doubt in real world scenarios you'll find yourself in a quiet room recording nothing with built in mics.
the preamps in the H4n ...
A belated answer that may be helpful to anyone searching in the future... Disclaimer: I have not read through other posts here, so this answer may repeat information discussed in more detail elsewhere.
I have been using the PCM-D50 + Mic2496 combination for over 4 years to make stealth recordings of rock shows in clubs and concert venues. I also bought ...
