What would you buy


I am a tube lover. I currently have a Rogue Chronus Magnum and Vandys 2 sig E. I'm thinking upgrading my system. I believe I can get 1K for the Rogue and add 5K for a total of 6K available to spend. planning to keep the Vandys but I feel that my taste desires a little more bass than what I'm getting now. Vandys are great in the mids , voices etc but it lacks some deep bass. The Rogue doesn't have an output for a sub woofer. Musical taste is classic rock, jazz and blues. Here is the question with 6K to spend in amp/pre, integrated or mono/amp, what would you buy?

Just one problem, atmasphere, and sorry to say because this may be the death knell, but you are absolutely right and I agree completely. You even suggest a mod, which I have done many times and agree with as well. Sorry. Sorry.
I’m impressed with what Rel subs  do for sound. Not only do they add bass but they add a bigger sound stage and air to your main speakers. They also connect to your speaker output of your amp, making a dedicated sub output unnecessary. I can’t argue against the swarm since I’ve never heard it. But I can see where it may have a WAF problem.

BTW, the Sumiko subs are a Rel clone and offer the same connections and results.
