Item : B0002E50MC Customer Reviews A godsend for my computers by .. Tcat Houser () I'm not as high end as some of the other reviewers. And I've been messing around with Via Voice, Dragon, yada-yada since 1990. The old saying GIGO (Garbage In, Garbage Out) applies to SR. I have spent many thousands on SR over the decades. If you look elsewhere on Amazon, you will see I'm a Dragon Fan. No more. Windows 7 (Beta 1) combined with a Shure SM-58 and this pre-amp going into a Light Snake (from Amazon), using "Speech" in Win 7 has totally changed my world. I plugged it in, turned the input and output knobs to '10', and went to work. *Friggin Amazing*. To credit MS, Speech was able to pretty much work without this pre-amp. However, Skype et al, no dice. There is one downside, and it has to do with physics. The 9V converter Requires a 9 volt AC output (due to the tube as the final stage). If you travel outside of North America (me), contact ART and order a 240 AC adapter. Or get a AC inverter . I'm going to order more of these babies and make them my new standard for everything audio. Can't beat the money by .. N. Gagnon (New England) I bought this unit because I needed a phantom power unit for a condenser mic and I am amazed with the results. If you have a project studio, you will be too. I've used this preamp to add tube warmth, depth and responsiveness to vocals and acoustic guitar. There is no substitute for tubes. If you're a pro, you'll probably spend more money on something else. For the rest of us.. it's a huge step up in sound vs the solid state preamps in most interfaces. Great DI box for non powered acoustic pick ups by .. Jay Dog (Toledo,Oh) Great DI box...A little touchy but smooth sounding, We use it for our seymore duncan no powered block pickups and is awsome for that. Have ran vocals through it live and is almost over powering but a tweak or 2 and bam! Smooth vocals..Should cost 4x as much. Buy it it's only a few bucks. You wont be disappointed. Excellent for Price by .. Tommy the Filmmaker () As a broke college student I couldn't afford much to go along with my protools rig but I wanted a tube preamp to add just that extra warmth in my home recordings. and for the $30 i spent it was worth it. Of course if you can afford to spend $75 or $150 by all means do so. The tube is so small in this thing and my only major complaint is there is no On/Off switch you ahve to unplug and plug everytime. but overall, if you're on a budget or just experimenting its worth it. you get... what you pay for by .. Joshua Gura () i know 'you get what you pay for' sounds negative, but that's not why i'm writing this review. i purchased this unit with the intention of modifying it. before i started to do that, i gave it a very good listen. the pots (volume knobs) seemed to adjust a couple different humming noises. only in certain positions on the dial did the noise subside to a low level. and mind you, that low level is anything but acceptable to anyone doing semi-pro work. basically, i was restricted to only one position on the gain knobs to work in, because the two different noise sources seemed to phase out there. i might as well have hot glued them in place, but for the resulting sound, it wouldnt even be worth the effort. if you are looking for a strictly entry level phantom power preamp, and dont care about noisy gear, this is a must buy. otherwise, dont waste your time.
