I'm not sure whether you've really heard both, TDL Ref Standard and IMF Reference Standard Professional Monitor MkIII or IV in your system side by side as I did.
First of all, these speakers are both extraordinary masterpieces of high end speaker's sound.
But their purpose is slightly different and consequently they also sounds differently a bit.
While IMF were dedicated to be high end studio distant field monitors, their also sounds more "analytically".Sound signature towards lighter, spacier but also "sharper", less pleasant sound, especially by listening some low profile recordings, when using in typical, non dumped home rooms without special acoustical treatment.
On the other side, TDL Reference Standard, I actually keep, was meant to be Reference Home speaker. Sound characteristic is tuned slightly to the warmer, more pleasant, practical sound, especially in reflexive home enviroment.
TDLs RS are definitely more suitable for long hours of exciting listening sessions.
So I would not say that one is better than other or vice versa. They are just made for different places and purposes.
But one thing is absolute true, without any single doubts.
Bass-subbass response of TDL RSM is second to none!
Even IMF RSPM can not come close or compete that TDL beasts within this specifical parameter! TDL RSM seems to be end of the road with regards to ideal "bass extasy" :)
