“I received my DACport today, and listening to it as I’m typing this, with smile on my face.
My initial impression, with about 5 hours of burn-in is very positive. I’ve listened to a variety of materials, including pop, jazz, light-rock, and classical… There doesn’t seem to be any emphasis on any particular frequency (i.e., frequency response sounds pretty “flat” to me; just as CEntrance claimed on their development blog). The soundstage is wide, but doesn’t seem as deep. Clarity is amazing; I can hear very small details without much effort.”
It is worth $450? For me I think it is. I plan to use it mainly with my MacBook Pro… I also really like the design. The cylinder-shaped case makes it easy to carry and store. The brushed-aluminum looks very nice. The velvet carrying case is also nice to have.
CEntrance, congratulations for creating a great product.”
