For the last few years, some McIntosh products have had their DA1.
It has been advertised as being replaceable with a future update/upgrade.
The new pre-amp released has the DA2.
I contacted (perhaps the wrong person) at McIntosh to inquire as to when the DA2 would be available to current DA1 owners. The reply was that there were no plans to do so.
I was hopeful that someone has more/different information. Thank you in advance.
