I've posted a thread about speaker suggestions and would like to now get some suggestions on what DAC/pre/pro and amp combo you guys suggest. http://forums.audioholics.com/forums/loudspeakers/85011-ascend-sierra-tower-raal-ribbon-upgrade.html I don't think the choice of components will depend on the speakers, but I'll take that into consideration if need be. I'm thinking of going with a UPA-200 for the amp and a XDA-2 for the DAC. My only source will be a PC so a DAC seems like a good choice. I won't be using a sub so bass management isn't an issue. I'm just looking for something that will complement the speakers as much as possible, and be nice and transparent. One thing I've never had to consider is aesthetics. I said it in the speaker thread that this will be downstairs and WAF comes into play big time. The reason I say this is the two components I'm looking at match well. I never though I'd have to consider that, but you just never know. Any other suggestions are very welcome for a nice combination that will interface with a PC. I do plan to use the USB feature so I don't have anything interfering with the signal path. I've never had a DAC before and my only experience with them is in the recording world with the audio interfaces I sold. I would go that route, but wonder if they would be right for my needs. If anyone can suggest a good model to look at I may consider that route. Thanks in advance.
