I purchased the DR100 to record classical musicians on-location as a smaller and lighter replacement for a much larger hard disk recorder and a pair of external mic preamps. I was hoping that the built-in XLR inputs and +48 V phantom power would be all I'd need for quality 2-channel recordings. After some live recordings of professional musicians as well as a bit of bench testing, I have mixed feelings about the unit.
The good: Using the stereo line input, the DR100 is capable of creating very clean, low noise, low distortion recordings. The DR100 uses Asahi Kasei delta-sigma "Audio4Pro" digital converters which are excellent sounding and have a very low inherent noise spectrum and a S/N ratio of better than 100 dB. The Tascam v1.10 firmware upgrade allows for 96kHz-24bit recording using those converters and the resulting .wav files are superb. The recorder can use SDHC cards up to 32GB, with single files of up to 2GB, so long recordings are no problem. The line input matches any nominal -10 dBv preamp or mixer output. The menus are easy to navigate and the file structure is straightforward. The fast USB2 interface makes it easy to transfer WAV files to any DAW. When backlit, the LCD display is quite readable and the peak signal LED is fast and bright. The peak LED lights at -2dB and the bargraph meters cover a range of -49dB to -1dB where the device clips. The display never reads "0dB".
The "not-so-good": Having built-in, phantom powered preamps was one of the reasons I choose the DR100 over the many other available flash-memory recorders. I own a 24-channel, 96k-24 bit "portable" rack HD system as well as a laptop-based 8-channel recorder and wanted a high quality, but small and light system for 2-track recordings that could be used with high-end external mics. The DR-100's built-in unidirectional mics are probably OK for "snapshot" recordings, but are not acceptable for any serious professional use. During my initial testing using both an external small mixer and external mic preamps, (going in through the 3.5 mm line input) the DR100 worked very well. However, the internal mic preamps are not all that great. Although the V1.10 firmware update does provide for 24 bit, 96kHz sampling as well as 44.1kHz and 48kHz, it does not allow for 88.2 kHz recording, which generally is a better choice for final conversion to 44.1/16 bit for publication on CDs. Tascam should seriously consider adding 88.2kHz sampling, even if it means dropping 48kHz.
The preamp gain is adequate for most any modern condenser microphone and many, but not all dynamic mics. At higher gain settings the preamps do have a fairly high internal noise, which becomes audible when the preamp is switched to the "H" (high) setting and the recording level control is advanced into a usable range. This is when the unit is used for classical music recording with a fairly wide dynamic range of 40-50 dB. For compressed pop, and rock recording this is a non-issue. However, I've encountered a much more serious problem (for my use). So far, I've had problems when using the DR100's internal +48V phantom power with several sets of widely available phantom powered mics. I connected a pair medium-output (-70dBV/Pa) ribbon mics and was not surprised that the DR100 did not have enough gain. I then tried a set of "active ribbons" (with phantom powered internal amplifiers and found that everything worked fine if only one mic was connected, but connecting both mics caused a very audible (-30dB) high-pitched buzzing noise in both inputs. This only occurred when running on the fully charged internal Li-ion battery. When running on the PS-520 external power supply/charger, the noise disappeared, even with both mics connected. To me this indicates a weak +48V phantom supply. I tried another set of mics, a pair of very popular small diaphragm omni condensers and even running on the external power supply I had serious noise generated when both mics were drawing current from the DR100's phantom power source.
Please note that all of the mics I tried all work fine using any of my Mackie, SECK, Yamaha, True and Presonus mixers and preamps with absolutely no problems.
Bottom line: I'm keeping the Tascam, but will be carrying a couple of external mic pres or a small mixer with it.
For reference, I did document the recording levels at various gain settings using the internal mic pres.
The signal source was a balanced mic simulator signal generator. Output -41.5dB, one channel driven, phantom power OFF, limiter OFF. Signal = 700 Hz sine wave.
Levels listed are the indicated recording levels on the LCD display:
1. Coarse Gain Switch set to "L"
Gain dial setting vs (LCD displayed recording level)
dial 10 (-42 dB)
dial 9 (-42 dB)
dial 8 (-44 dB)
dial 7 (-47 dB)
2. Coarse Gain Switch set to "M"
dial 10 (-20 dB)
dial 9 (-20 dB)
dial 8 (-21 dB)
dial 7 (-24 dB)
dial 6 (-30 dB)
dial 5 (-34 dB)
dial 4 (-40 dB)
dial 3 (-45 dB)
3. Coarse Gain Switch set to "H"
dial 7.5 (-1 dB) clipping
dial 7 (-3 dB)
dial 6.5 (-6 dB)
dial 6 (-8 dB)
dial 5 (-12 dB)
dial 4 (-17 dB)
dial 3 (-22 dB)
dial 2 (-27 dB)
dial 1 (-29 dB)
dial 0 (-29 dB)
As noted above, the actual usable range of the attenuator dials is from "1" to "9" representing a maximum range of 29 dB. Changing the dial settings between "0" and "1" , and between "9" and "10" has no effect at all.
For actual acoustic recordings using a pair of sensitive, high output external cardioid mics, recording classical music with a peak acoustic level hitting around 85 dB SPL, I needed to set the coarse switch to "H" and the attenuator to "7.5" to get good recordings that peaked at around -4 dB or -3 dB on the DR 100 meters.
Other than the "wimpy" phantom power supply, I do like this recorder. It's capable of making fine, professional level recordings as long as you are aware of its limitations.

Used for voice overs for News PKGs. Great little MP3 recorder when paired with a Shure SM7 mic. Recorder mounts on desktop and just drag and drop files to the bin you are editing out of, easy peasy.

It's too soon to give a full review (as I've used it less than a dozen times), but so far, so good! I haven't had any problems with it, and it seems fairly easy to use. I need to become a bit more familiar with some of the controls and build my savvy on the usage of the mics, settings, etc. However, to me it was a a great purchase. I did a lot of research and I have no complaints! Purchase a power adaptor and a larger SD card (I bought at 16gb), which you'll eventually need if you plan to use this device while traveling and time will pass in-between file downloads. Another thing - it's well-built! I dropped it (wihle in it's soft, protective case that comes along wtih the purchase), and not a single ding. Not flimsy at all, so it'll take me a long way. I only wish it had some sort of carrying case/pouch with a shoulder/body strap. While "on location", I need it to be recording and not forced to carry it as it is a bit bulky in-hand. I'll come back with more info as my experiences grow.

Tascam has always been at the forefront of technology with their first compact flash rackmount digital recorder. Although its style was more along the lines of a touring case, it made a clear leap that said digital recording is the way of the future and audio journalists should take note. Complete with adjustable gain, xlr jacks, and VU meters its only real setback was the oversize formfactor and the power consumption.
Later came Tascam's redesigned user interface with the ipod like wheel. The DR-1 and DR-07 were certainly optimized for specific uses such as acoustical guitar, and both included built in exceptional quality stereo microphones. The DR1 included a lithium ion rechargable battery while the DR-07 ran on AA cells.
With the introduction of the DR-100 Tascam answers almost everyone's needs. 96 kbps recording is now standard, as are xlr inputs (mic level only - I'm bothered by not having line level XLR) and two battery types, both lithium ion and AA. You get to specify which battery is "primary" and which is "backup" to get through long recordings. That feature alone can save you on an overtime job where you need 8 hours of battery power without interruption. The XLR mics have a switchable filter for environmental noise and also a switchable 48 VDC phantom power. The reason I am bummed about no line level XLR is you pick up another 20dB s/n at line level when you connect it to a recording board output, and while it does have a line level in, it is only an unbalanced TRS 3.5 mm jack, same for the line out. Most recording boards are not going to have unbalanced 3.5 mm stereo plugs.
Sad note here on such a great machine - if you have a mixture of microphones, both TRS 3.5mm mono or stereo and XLR mics you will only be able to use the XLR mics with this recorder. While you can buy transformers to convert unbalanced TRS mics to XLR format, that increases the size and decreases the quality somewhat. I would have rather had a 3.5mm mic level input for existing mics I own and used the XLR jacks for switchable mic/line in/out. If all your mics are XLR this will not be a problem, but the first time you need to run an old 3.5mm mic with this recorder you will be sorely dissapointed.
Memory comes with a 2GB SD card and can be used with up to a 32GB SDHC c4 card if you want to record for a week. Tascam has been reasonably generous with cases and microphone options, but seems to omit the DC power supply to run the unit off battery or to charge the li-ion cell. Figure another $25 for the charger and you are set to go. I see what they are doing - keeping the street price under $400 for this model by omitting the power supply, but hey guys, realistically everyone needs a power suppy.
The last bit on the -100 model - because it does support many asked for features the package has grown just a bit. It's still exceptionally smaller than their rackmount recorder! Feature wise, it has grown considerably and is half the price now.
The only real competition for the Tascam dr100 is the Marantz PMD661 which was recently announced. I've compared the PMD's internal mics and they do not stand up to the tascam - you'll be using remote mics all the time on the PMD661. On the other hand the PMD661 DOES have line level XLR jacks which means you can pop it on the end of the mixing board and run with it. The PMD661 also has half the runtime of the dual battery tascam. If tascam hadn't used the 3.5mm TRS jack for line in (they are really noisy compared to XLR) I'd say beyond a doubt stick with this unit, but if you work the mixing board, or have axcess to the outputs, the PMD661 will make better 4 hour recordings with 20dB better signal to noise.
If you sit in the audience the Tascam will be best, if you sit in the booth the Marantz will be best.
