I'm quite late to this thread, but I recently purchased an ART USB Dual Pre Microphone Preamp and have been quite happy with it so far. I have not used its USB connectivity, but jacked its outputs into my Delta 1010 and it sounds very good - it's nice and quiet and had no trouble providing phantom power to a Rode NT1A using battery power. It's a USB1.1 device so if I were to use it as a USB audio device, I'd only get 16 bits and either 44.1 or 48 KHz from it, but that's fine for my use. It takes either 1/4" or XLR inputs (both balanced) and gives 1/4" balanced outputs. It can take power from a battery, external power supply, or USB connection. I have not tried providing phantom power to a mic using the USB connection. I don't think this is quite what the original poster was looking for, but so far I've been very happy with this and wanted to mention its existence. -- ====================================================================== Joe Hartley - UNIX/network Consultant - jh@xxxxxxxxxxxx Without deviation from the norm, "progress" is not possible. - FZappa _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
