Best for Classic/Progressive Rock and Blues
Sticking with the vintage theme of L100 and the 4311 JBLs, another option is to redo the XO for them.  I believe Troels Gravesen had worked one up to offer.  I had the 4311s but alas elected to go modern.  No regrets but I hated to part with them.... 
ribbons vs domes and sibilance
@roxy54 what speakers (tweeters) have you owned and what current Be speakers are you referring to?  Might DIY something soon and will be making that choice.    
Component contributions to “sound stage”
This is a valid question about one's system.  To reduce an answer to "it has to be in the recording" is not helpful.  Of course.  OP didn't ask how to make all of his music have same.  I think he gets that.  But yes, speakers with high quality dri... 
The molecular level explanation of "cable burn-in"
Reminds me of a co-worker who would write such equations to describe various other coworkers' personalities and quirks.  Was quite funny actually.  Yes, they were aware of it.    
For the love of...kits?
@hilde45 as an owner of a "kit" Speaker I cannot be more happy.  Sure, I punted and had cabs built by Lee Taylor but they sound sublime for a 2W stand set up.  Based on Scanspeak and top XO components.  NADA kit from Madisound.  Worth twice what I... 
Microphonics, Feedback and Bob Carver
@erik_squires you said recently "welcome to AG where you get what you pay for and a whole lot less".  I thought that was brilliant (comeback) but I'd say this is far from worth-less.  And like the prior,  I'm barely hanging on past, the speaker ac... 
The $10,000 Question
OP,  OK I'll mention Raven.  Love mine and 20 wpc in my midsized room seems plenty.  2w stand speakers at about 87db.  Your room is15x15 and not sure of your next speaker's efficiency  it might be a tad low on power.  Raven does have 80hz hi-pass ... 
Signal tube versus power tube, sound impact?
My experience is like @ghasley.  Small tubes in pre stages made way more noticeable change than output.  Using NOS recommendations from both maker (Raven) and Brent Jesse I chose military and or scientific grade pre tubes.  Stage expanded and bass... 
Comparing streamer/DACs between $5-10k
Innuos and their Sense app seem pretty straightforward and simple to use.  But not much for meta-data on artists etc.  Lineup spans price points and tech.  Zen(ith) line rips/storage, Pulse do not.  Most require DAC.   
Bananas rule, spades drool. End of discussion.
OP, I could have sworn a couple years ago or so you asked AG members for a good clamp/no solder spade recommendation.  Change of heart or bad experience?  
Cable Break In for the Naysayers
It's a broad general statement that declares that "i know that there's nothing I don't know".  That's my only point.   It's an over-reach imho.  Im not at all saying that we can't measure countless things with instruments  better than we can ourse... 
Cable Break In for the Naysayers
Without any implied agreement or disagreement with the OP, the idea that "if it can't be measured it can't be real" (to paraphrase) cannot in any way be a valid position. (Not that above poster necessarily agrees with it either, while many do).  S... 
Newer Blues Artists or Recordings
Kingfish,  good entry.  Not new but new to me this last year or two is Tab Benoit.  Mix of southern Delta /Zydeco blues guitar/vocal.  Some great Telarc recordings too once he hit his stride.      
All speakers have a little EQ built in
@audiokinesis can you expand on how low, or how much of the phase curve that's low inductance, at low impedance is acceptable for most tube gear?  I don't want to hijack the thread but isn't this the crux of amp/speaker "synergy" save perhaps effi... 
Upgraded my cables and they transformed my system!!!
@vthokie83 any particular designs you'll be making you can share?   Built my own RCA and speaker cables so im curious what length others go to.
