Pardales...
Geoff Poor of BAT had originally recommended the 55 to me as a bi-amp option... One at first, add one later on so actually two VK55... and run them bridged to 110 wpc. "Well, sure thing, Geoff!" If I had Geoff's money I'd throw mine away... but he's a great guy and has provided me a lot of good insights along the way... and by the by, their head of sales... go figure... Having heard the JR's with less power, though not at high volume levels, "Drive them?" Sure. Drive them at high levels I'd think so but can't testify to it. With 87db efficiency the JR's, as many others with that level of efficiency, can be hungry for power to develop signals in the upper ranges of the volume happy end of things..and provide a vibrant, and dynamic presentation that will approach a live recreation.
I too listen 90% of the time to levels that allow conversation, or slightly above.... BUT there are those time... and the only thing that controls the volume is my fear of damaging the JR's... as I have sufficient power with the vk500, to get them up there. Another thread here about tube power v. solid state power, addresses that question in general. For I posed the same Q, with some great insights... I've talked with folks that are running N802's with 60 wpc tube amps... heard the JR's on 30 wpc... so it will work... Albert V. designed the JR's with the notion to get the very best sound out of them with bi-amping in mind... but not the rule, and solely optional. Personally, I am thinking to add a vk60, or vk75 up there, and they ain't but 5 to 15 wpc larger in current development than the VK55. Remember the top end of the JRs is an 8 ohm load... the bottom is 4. that's where Albert gets the 6 ohm overall. He also intended them to be at least bi-wired.
I'd think there are plenty of tube amps driving the JR's...and am curious why more haven't contributed in this particular thread to that extent, indicating their current or past matchups with various amps & the JRS . some of the reviews on the JRs did exactly that . Good luck!
