Chgolatin2,
I have heard both the JR(mkI) and SR(mkI). They both are great speakers and one of the best in it's respective price class. In absolute and relative terms, to me, the SRs are better and they should be for the price difference. What's more important is your room. If your room is small to medium, you can get by and save money and buy the JRs. But if you have a bigger room like I do, I went with the SRs. But keep in mind, as you go up to the SRs, your equipment should follow up and be in-line too. You need a bigger more powerful amp that's for sure. I also felt that the front end (player and preamp) should step up too, to get the maximum potential of these speakers. But that is not a hard rule, but the amp piece must be mated accordingly. To get the SRs moving and sound correctly, do not put a low powered amp (especially driving the Bass module section). Anything less that 200 solid state watts will not sound that good. So definitely give the bass module a strong, powerful, refined amp as you can afford. If you get the JRs, you don't have get a too powerful amp as you would for the SRs. So it's not as simple as just buying a larger speaker, but the aftershocks that go along with it. Be prepared for the down stream affects(more money spent) when you go up to the larger SRs, so pick wisely.
Anyways, both speakers would sound great if mated with the right equipment and setup properly. You will be amazed of the 3D soundstage, precise imaging, true timber of instruments and voices, thunderous tight, deep,fast, defined bass, and great separation of the notes, but performs cohesively to convincing manner. Either one of these on the used market is a great buy especially the mark I versions, it's a steal IMO.
