Speakers with warm treble and good bass

Hi good question based on what you have tried . I have a friend that is a former Rogue, Modwright, Acoustic Zen , Dahli dealer. He also had many more brands . He has multiple systems in his home and office , including a dedicated room for listening as well as a dedicated room to house equipment with its own power panel . He too favors Rogue equipment . One of his systems contains the updated Rogue Mono blocs and their top pre amp . He has  the Adagio's in custom burl walnut and Acoustic Zens best cables . Also in the rotation are a pair of Dahli's and he runs a pair of Jl Fathom v2's in 10". The room has extensive acoustic treatment and is tuned with with his $5k meter . Your tastes sound very similar to yours, and this is why I jumped in . He offered me the Acoustic Zens as they were replaced by the Joseph Audio Pulsars . They are SWEET ! Also IMHO you are under powered . He has a Chronus II in his office and I tried  my Zu Omens and Klipsh Heresy II 's with it for giggles . It was nice . But I have a pair of JBL  4312a's on 28" Sound Anchor stands and any tubes below 100 watts or SS below 200 watts won't work . You would hate these , but it's just my example . So to answer your question , audition the Pulsars , but at $7k and 5k for subs plus cables , thats a lot of green . Also , have you rolled any tubes ? I recently moved into entry level low powered tubes . I have a Rogue RP-1 and a Dennis Had Set amp . The first thing I did was replace the JJ's in the Rogue. I obtained NOS RCA , Mullard and Tekefunkens, settling on the Tele's. I have 6 gain tubes , and 4 rectifier tubes all NOS for the power amp. I also have 3 pairs of current production power tubes . So in closing , audition the Pulsars , they sound fabulous and have a huge soundstage . Consider more POWER . But first , TRY ROLLING THE SMALL TUBES IN YOUR AMP WITH NOS . Telefunken and black plate RCA will be what you will like . Also the Tesla Red Tips, are very liquid . The Red Lion KT-88 reissues are great. The small tubes will have the biggest change in your system and be the most cost effective . Anyway , I hope this helps , and happy listening . Regards , Mike B.

Jwglista,

Find a pair of Spendor S8e speakers and don't look back.

Give your Spatial Audio M3 Turbos a chance to break in and see what you think. I have the M3s (non-turbo) and have not had any listener fatigue whatsoever. I sold my Klipschorns after 17 years because of treble harshness that was causing fatigue, and bought the M3s after listening to most of the speakers you list and more. And to get the best of all worlds, I added a pair of Goldenear Forcefield 4 subs. Goldenear bass is sublime, and they've been a perfect match for the M3s, which have a warm, musical bass of their own. 

I own a pair of Vienna Acoustics Mahlers. They have the sound you are looking for. Dual 10" woofers on each speaker as well as two 7" mids and a 1.2" tweeter. You can find these used for good prices,but beware, the wood veneers tend to fade. Mine are gloss black and have not faded a bit. I am running a McIntosh MC452 amp, C52 preamp and a MPC1500 power conditioner. Sound is liquid smooth and has tremendous bass. No need for a sub here.  These were $13,000.00 new.
I have seen them for sale here for around $4500.00. 
if you can find a pair to listen to, I think you will love them.  They weigh something like 160 pounds each. 4 ohm, 91dB.  Big speaker. My room is 14' x 17' and they sound awesome, but will perform in a much bigger room too.  

Gamut M5 or M7. Best musical satisfying sound I ever experienced. I had owned 70% of the suggestion here.
