I have a HC2 non-DR with my XS2.
Should I upgrade to HC2-DR with a special kit?
When I tried to replace the XS2-HC2 with SN3 sound came out too big… noisy… can I connect the SN3 to my HC2-non DR ?
Will it do any effect?
Speakers are Proac D2R
You can’t upgrade the Hicap to dr. Naim doesn’t do it anymore.
Yes, you can connect your Hicap to the SN3. Can’t say if you will prefer or not, because even with the Hicap dr, opinions vary. Most prefer however.
After around 10/12 years, you need also to send the Hicap for service.
