Mrquery,
Here is our humble comment on your set-up.
1) Your tube + small bookshelf monitor set-up is geared towards vocals, jazz and such music. That system will not be optimized for rock and roll. Sorry to disappoint you but there is no system that can play all types of music optimally (of course there are systems that can play all of them well but there is always something that each system will play particularly better). There will be sacrifices so we always try to understand what our customers listen to most of the time and tailor our recommendation to that preference. However, here are a few area where we can improve your rock and roll on.
2) Please fax/email us your room set-up. The square configuration could be a little tricky since it can result to cancellation of certain signals; thus you do not hear the full range. We need other data such as wall material, ceiling height as well as sitting position. Then we will run those variables using our simulation software and provide you some optimized set-up suggestions. Hopefully this will help bring out the bass you have been looking for.
3) We can use cost efficient tweaks to imrpove your system. Change of pre-amp tubes to those that are faster sounding, caps upgrade to faster caps or we can use silver cables ... all these can be done to speed up the music and improve bass.
4) Adding a sub is doable... if you wish we have an Aurum sub that you can home audition to see if it addresses your need for the extra extension. Check out the SW-10 Aurum sub.

We also have an amp that will allow you to tube roll 4 different types (EL-34, 6CA7, KT-88, 6550) but let us start working with your current system first. Why spend more if we can find ways to get what you want without extra expenses.
Visit us if you have time and we can talk in person. Easier because i can draw different set-ups on paper.
