I owned the VR-4JRs and have auditioned the VR-4SRs. The SRs are better in that they are more revealing of musical detail than the JRs and go much lower with stronger bass. I think either would work in your room but small to medium sized rooms need not apply.
Ive never had a problem with VSA customer service. My emails and calls were all handled in a prompt and professional manner. I am sorry to hear that others have had problems.
Speaking as a fan of VSA speakers, you may also want to look into the Consonance M15 speakers. They are an amazing speaker. I feel that they are much better than the VR-4JR and VR-4SR. In my opinion the M15s compete with, and are better than, the VSA DB-99. The M15s are probably the most engaging speakers I have listened to. They really pulled me into the music and made me stop analyzing the sound. All the audiophile stuff is there (imaging, wide/deep soundstage, detail, bass extension, treble extension, etc.) but after the first song or two I stopped focusing on all that. I just listened to the music.
Enjoy!
