So, I'm thinking about improving the sound on my primary, computer connected audio setup, and wondering what its existing strengths and weaknesses might be in the forum's opinion. I'm not particularly an expert on audio hardware, and I'm aware this setup is a lot less complex than many people's. The chain as it stands is: U46 XL (a USB soundcard) > Pioneer A10 (via aux) > Wharfedale Diamond 220s ESI - Product Archive: U46 XL Pioneer A-10 Amplifier | Product overview | What Hi-Fi? Wharfedale Diamond 220 review | What Hi-Fi? I also have a Steinberg UR22 Mk II which I've not yet used, but could possibly use in the place of the U46 XL - although the UR22 Mk II having its own "output" level knob put me off doing that previously (and there's no concrete information on which setting would essentially negate this), and I'm not sure if it would be better. Headphones, when used, tend to get plugged into the A10, but I'm really most interested in speaker listening. All of the content going through it is lossless digital audio from the PC, which uses the soundcard. My gut instinct is that the soundcard is the weak link, and a better soundcard of some sort would serve the most improvement. Unfortunately, information on good options is really hard to come by, geared mostly to people looking for a DAC for headphone listening. I do want to stay external (USB) with that, so not an internal card. I'm thinking I'd need to spend significantly more to improve on the speakers or amplifier, both being fairly budget but considered among the best in their class. Any thoughts? I'm not massively unhappy with the setup or fighting any obvious issues, although I do feel I can get more from the chain.
