No the above mentioned orchestral tape certainly aint my personal favorite after all
My favorite orchestral tape is still a 7,5 ips /per 525 tape (also a one of a kind recording afaik ).
I bought this tape from a renowned dutch recording engineer .
It was recorded on a telefunken M 15 A back up tape machine , hence the low 7.5 ips tape speed , its taken from a live broadcast recording
It can easily rival the SM 900, 911, 468 studio tapes on 15 ips ime , the recording quality is more important then the tape format / speed .
Ps He also said he never liked to use the studers ( A 80 ) on live recordings but prefered the telefunkens as being more reliable .
