…oh, goys and birls…and uncles…
this is more than just funny…!
first, it’s such a nice proof of personal taste and different perspectives…
then, it’s such a nice antidote to all the endless kindergarten discussions about the doubtless and countless miracles of an ten year old classic electronic music instrument…
and since u, uncle gordon, seem to like straight digital converting, u might wanna consider a digital mixer…it’s really hard to tell these days, which pre amps and converters do actually not have their origins in china, to be honest…
even swedish gear can’t go totally without supplies from there…
so quality measurement can not be made just by “made in china” or made elsewhere…
ur a&h board comes from times where they really had to catch up to stay in business…
so, yes, mixing boards from that time had really cheap pre amps…
but since they became a big brand in dj mixers, they really nail it again, when it comes to pre amps and converters…
and overall, british gear has a good call these days, again…
behringer bought all the midas knowhow for good reasons… 
if u can find a midas console u really get best of both worlds…good analog mixing and good interfacing…
but also the actual digital boards from a&h do a really god job…in both ways…
the qu series sounds really decent…
and if u wanna catch as many channels as possible in one go, all analog solutions will mean big bux to pay…and since ur still impressed by ot’s capabilities, switching to a digital mixer/interface solution might be best bang for ur buck…
i don’t think, whatever the russian tech guy will do to that board will really help…
and what he will cost u, can also buy u the option to get rid of stereobus recordings and start to pick single channels straight at once instead…
and if it’s not about single recordings at all, well then keep ur mixing deck as it is, buy an analog heat and run the main bus through it… that will make ur thin mixer sound like a fad ssl…
