Wow - excellent!
I heard a pair of IMF TLS50 in a friends 2nd system a few years ago - we'd been listening to his 'posh' main system with expensive Opera speakers for quite a while when for a laugh he fired up the 2nd system that resides in another room. I much preferred the system with the TLS50, and I think that was mainly down to the speakers.
I don't know the Response 2S, but I am a big fan of the original Proac Response 2 - a pair replaced Quad 63, and totally showed them the door in every way, imo. I'd imagine that the presentation is very different between the IMF and Proac speakers - both good, just different!
Maybe it's an age thing - but my system seems to be slowly heading backwards in time as well. I can now afford to buy things I could only ogle at enviously back in the day so I'm indulging myself a bit.
They made good kit back then that looked the biz.

Do the IMF speakers sound better with the grilles on? The reason for asking is that the HF drive units are very close to the recessed baffle edge and there will be horrible diffraction effects, unless the grille incorporates some felt or similar to deal with that. If there's no felt in the grille, then a cheap tweak is to cut some thickish felt material into rings and place these around the tweeter and super-tweeter domes.
I saw a visual representation of this sort of diffraction last week at the Institute of Acoustics 'Reproduced Sound' conference - some clever people at the National Physical Laboratory (NPL) have found a way of using laser interferometry to produce a moving video of sound waves. It's very interesting (but perhaps not surprising) to see what happens when a propagating sound wave produced by a tweeter hits a hard edge!
My mum has one that would be perfect - just need to wait for her to die then I will have the room and the sideboard
I do like that! The amp looks great, I'm thinking of setting up a vintage system myself.
The Response 2S are also excellent speakers. I enjoyed them greatly during the two years I had them. You are quite right in saying both are good, just different. If I could have afforded to keep both I would have but on balance I felt that the IMFs had better synergy with my vintage gear and just seemed to give me more of the sound that I was looking for. Big transmission lines do real bass in a way that a small ported box cannot. Given the fact that the driver layout of the IMFs looks like a dog's dinner, they image surprisingly well and produce a big convincing soundstage that has real depth and height. However, the Proacs probably have the edge in terms of 'holographic' imaging and detail retrieval.
This. I love the Marantz gear that you have too. Simply gorgeous. Proper hi-fi! My first job back in 1978 was as a Saturday boy in a hifi shop and my first system was Sansui SR222 mk1, JVC JAS-11G, AR18 mk1. I loved that system and had it for donkey's years. When I saw the Kenwood amp for sale in Glasgow it gave me the idea of building a 'high-end' version of my original system. My dream was to buy AR3a speakers to go with the Kenwood and Sony. I did buy a pair from ebay but all the original drivers had been replaced so they went back. I'm very happy with the IMFs so I'm no longer searching for AR3as.
Great idea! I listen with the grills on as I have mental cats. I will definitely get some felt and experiment a bit.
Edit - I recently restored a pair of AR94s that had a square of felt about 7-10mm thick around the tweeter (see pic). What thickness would you recommend? Also should the ring be quite tight to the each tweeter dome or should I try to frame both tweeter and supertweeter within a triangularish felt box a bit like the AR94s?
