Two guys in my Boston area audio group used to listen much more to analog. After purchasing or modifying their DACs, they are listening to a lot of digital now. I don't actually know if they prefer one over the other anymore. As an all analog guy, I admit that it has me wondering. Digital has gotten extremely good lately.
Back on topic. I am thinking of replacing my three Furutech IEC connectors with the latest NFC model. I don't have any wall outlets or plates in my system.
I've heard RtR crush digital, but otoh a digital rip of the RtR is very, very difficult to identify from the original. Something to think about...
I recommend adding as much NCF as your budget allows. IECs are generally very easy to switch out, but a bit of filing and/or a couple of small drill holes may be required as the sizes and bolt hole patterns are not standardized, and some, including the Furutech can be front or back mounted. If there wasn't an IEC or it's too different I'll have Front Panel Express machine me an adapter plate. M3 or #4 screws seem to work well.
