Will tubes rock?

Hi Pinetop; I feel like I've got to "tippy toe" here 'cuz for the most part I don't feel that a good tube amp can rock like a good SS amp can. I say this because I recently compared, head to head, a Sonic Frontiers Line 2 (110 wpc), and my McCormack DNA-2DX (300 wpc). BTW each of these amps lists for $5K. And while the SF tube amp had much going for it, it simply lacked the rhythmic drive and control of the bass like the McCormack has for R&R music. The bass of the tube amp was plenty deep, but lacked quickness and control, in fact it was no contest. I listened to the SF Line 2 for over three weeks, and enjoyed it very much on music that did not depend on quick, articulate bass. I'd recommend a good SS amp such as McCormack's DNA.5 or DNA-1. I should note that I use Sonic Frontiers Line 2 pre-amp (tubed), and like the combination very much. Happy Hunting. Craig.

.......major Typo above, Line 2 should be POWER 2, except for the last sentence which is correct. Sorry.

Music Reference RM200 Tube amp by Rodger Modjesky was $3600 retail-purch. new. $2300. 6550C in it now. JJKT88 about to roll. This push pull amp has never failed to rock from whatever was played thru it. Satrianni to space music. A little laid back for some. This room is not to large (13X25) w/burbur carpet. Rest of sytem: Sound Wave Point Source 4.5, 2.5 & Diolog center speakers by vero research inc. w/Vandersteen 2WQ subs. ARC LS10 ss pre & Anthem AVM2surround/AVC3amp & Straightwire Crescendo/BlacSilc/Seranade/Infolink cables. comprise 2ch. & theatre.

(this is for my brother, Pinetop14) The listening room is approx. 14x12X14

Given the room dimensions (though it's pretty square which can be a big problem) you could feasibly rock with a little 2A3 3 watt/channel amp if you paired it with efficient speakers. Most any linear (as neutral as you like it) push/pull amp would widen your speaker options. I have already experimented with different tubes (output and driver) in my 300B amp and can extend the frequency extremes, though with losing some midrange roundness, just by changing the 6922 tube.
