I'll gladly offer my two cents as well - hope it helps.
It was a fortunate coincidence to be located near Portico world headquarters,
and Tristan Rhodes was extremely generous in allowing me to live with several pieces
for a couple of weeks (pretty good idea business wise, as I now own a 5012, 5032, 5043
and a 5042).
Just my experience, but for tracking I found I liked the pre-amp a lot more when
paired with the EQ module, which is why I initially opted for the 5032 over the 5012.
I found it fantastic for acoustic guitar (both picking and strumming - using both a fairly
large Martin and a small, cheap Yamaha in Nashville tuning). However, it really quite
nice for everything else I have tried with it. I have the usual suspects as other options
(Pacifica, 610, etc.) but I just really love sound of these little guys.
I was initially using the compressor and the true tape parked on the ever so popular
two bus (or buss - haven't seen the results of the poll yet) but also found I liked the
sound of the pre (silk in) washed over just about everything, which is how I ended up
with a 5012 also.
All three together is perhaps a little too much color, but the nice thing about the units
is each has a color mode and clean mode (with or without silk on the pres, feedback
or feed forward on the comp, varying degrees of saturation on the tape unit).
This offers some really nice flexibility.
And as many others have mentioned, RND seems to be a small but very well run
company. I have had great customer service, and was even allowed to borrow a 5043
when mine needed to have a repair.
I wish you the best of luck in your search!
