OK, so I've been an "audiophile" for 20 years. But I'm not a hard-core audiophile in the sense that I don't spend my freetime auditioning interconnect cables or "breaking in" solid state audio gear. There are great improvements in higher end equipment, and even interconnects, but I'm not a sucker and don't subscribe to $20 per foot speaker cable. I own a pair of Thiel CS2.3 speakers with the last of the breed, and rather venerable, Adcom GFP-750 preamp (which even today, is a fantastic silent pre-amp compared to anything under $2,000) and the Adcom GFA-5802, which also is a venerable solid-state amplifier receiving excellent reviews from high-end audiophile magazines at the time, and continues to fetch an excellent price on E-bay. I never expected that the slim devices Transporter would sound better, or even as good as, my Adcom GCD-750 CD player as a source component. I was going to be rather content with the unit if it sounded pretty good, but offered the convenience features of an audio server. When I ripped some uncompressed audio from my CDs and queued up some tunes in the transporter, I was literally amazed by the quality of sound from the Transporter. It surpassed my trusty old friend, the GCD-750, with a wider sound stage, more "air" and transparancy between the performers, warmer mid-range, cleaner highs, and more slam in the bass. And my GCD-750 is a great CD player. I wouldn't say it is night and day, but it is a significant improvement. I was skeptical of the format of a music server, so the fact that it offered BETTER music reproduction than my GCD-750 source is truely a remarkable achievement for a unit you can pick up for $1700, if you watch the sales. The feature set is also stunning and exceeded, by far, my expectations. With over 600 CDs ripped into the unit, I am now like a baby in a candy shop with every single tune in my collection not more than 5-10 seconds away. I remember carefully opening the unit as not to destroy any of the packaging expecting I might take advantage of the 30-day return policy. Well, the box and packaging is now downstairs in the basement for good. It is truly the finest audio component I've ever purchased. At $1800 it's not chump change, but if you've been thinking about a music server, or even a stand-alone DAC, you can't go wrong with the Logitech Transporter.
