I use an Aqvox Phono 2CI phono preamp. It has an interesting feature: output coupling capacitors that can be defeated/bypassed to purportedly offer better sound quality. The catch is this: the integrated amplifier (in my case) or preamp upstream apparently must have input coupling capacitors whose main function is to block DC (so I've read) if the output capacitors on the Aqvox are to be bypassed. I've also read that with tube preamplifiers this DC blocking is not an issue (don't know whether this is true or not and why it would be, or whether tube based preamps or integrateds would actually have input coupling capacitors); anyone that comes forth can enlighten/educate me on this. I'm using a Unison Research Triode 25 integrated amplifier and currently have an email in to tech support at Unison Research asking them if I would be able to bypass the output capacitors in the Aqvox without risking damage to the integrated or speakers, which is a possibility from what I understand if a) the Triode 25 does not have input coupling capacitors or b) it will be susceptible to DC if it does not. Thanks for any info.
