The first two batches sold out before we had a chance to email the main diyAudio store mailing list, and the reviews are in. Feedback is that it also does make a great little pre-amp. Batch 3 of the diyAudio / Pete Millett collaboration headphone amplifier the Starving Student II is now available, so grab your own now, read the reviews on the product page, or visit the SSII discussion thread on diyAudio.
