Well I have a Crack + speedball coming for dedicated audio use which will be paired with my scd-555es. So I need another amp for computer based stuff, and I figure just to get a portable amp so it can do double duty. I didnt really want to spend more money on a portable than the home amp so I could power these things, but that might just be what needs to happen... Maybe I will get one of those Lehmen clones and use that for the computer. Just need to get an inexpensive Dac until I can get a real nice one that will maybe take over the duties of the SCD-555es and then I wont need the computer amp anymore, (as then the Crack will be mated to that good dac which now would be on the computer) and then it nice to have a good portable amp. I dont have an audiophile quality powercenter, maybe I should just get one of those an put the 555 near the computer (as of now they are physically about 15 feet apart wall socket wise) and then change out cables to the crack.
Well either way I hope this explains why I would like to use a portable. If I could get a dac that sounded better than the 555es then I would just get that and run PC audio and perhaps download the CDs I have or just spin em in the computer and play em to the DAC and not have a two station thing going on in the first place.
