Speaker advice for listening to Blues music


Hi, new to the forum, and hoping I can get some help finding the right speakers... I'm a Blues guitar player and have a dedicated music room for my guitars/amps. I usually spend time playing my guitars and recently decided to setup a decent system for listening to my Blues music. I first started with a Marantz integrated (PM8005) and some Kef R300, source is a Marantz ND8006 and I mostly play FLAC files from a NAS, but also started streaming from Spotify and now trying Tidal. This setup was great at first, very revealing, but found the R300 were not the right speakers for the kind of music I listen to, but they were great for some Jazz and did well with good recordings, which most of my Blues recordings weren't, specially live albums. I also found them to be a little boomy in that small room (12' X 12'), so I moved them to the living room instead and added a matching center, they're perfect there.

Next came the LS50, read so much about them I had to get a pair to try. Wow! I still can't believe what these small speakers can do, the details I hear, soundstage, imaging, it's all there. But, just like the R300, since they're so revealing they're horrible with my favorite Blues recordings. It's great to listen to excellent recordings and enjoy the music these speakers are making but I want to enjoy MY music, the Blues greats I've been listening to for over 30 years. If it sounds great in the car then I should be able to find the right gear to duplicate at home, right? On some good Blues recordings it sounds excellent, but most of my favorites aren't good recordings.

Since I only play my guitars through old Fender amps I figured I should replace the Marantz integrated with a tube amp, so next came the PrimaLuna integrated. I wanted to get a "warmer" sound and hope it'll fix the issues I was having with most crappy recordings... I want to hear BB's beautiful guitar tone and crank it up, without hurting my ears. Both Kefs were too fatiguing to listen to. And on most live recordings guitars sound way too thin and bright, not what I'm used to hearing. A good example is Albert King's Wednesday Night in San Francisco, that Flying V can be painful to listen to after a couple of minutes! Not so in the car or even just using headphones and my laptop. I understand that it's because the system is more revealing, but is it possible to have both, revealing and musical so that one can enjoy the music they love? The PrimaLuna did help and it's staying, I like what I'm hearing so far, and I get to play with tubes, something I enjoy doing already :)

Right now I'm breaking in some Wharfedale Denton 80th, I wanted to try something with a soft dome tweeter, something less fatiguing than the LS50. I'm at 70+ hours so far and they're sounding much better, not as fatiguing, but something is missing... I prefer the LS50's soundstage and details, but they're both not that great for electric guitar. The Dentons are more forgiving but I don't find them musical and they don't disappear like the LS50s do.

So what are my choices? Do I stick with bookshelf, try some floor standing? What about single driver speakers (Omega, Zu...)? Are those the answer to what I'm looking for? I need something more forgiving, musical, efficient so I can crank it up when I feel like playing along some times... I want the guitar to sound full and not thin and bright. It's a small room and not a lot of space due to my guitar gear. My budget is also limited, would like to keep it under $2k, I already have a hobby and don't want this to get out of control :)

Forgot to mention, I also have a Rel sub, so not too worried about the low end. Sorry for the long post and thanks for any help!

Read some reviews on LSA Statements monitors, they go to 39hz, 6ohm 87db, have a ribbon tweeter with auicaps. Maybe the tone your missing is the monitors your looking at don't go low enough, used there $800 to $1000, I enjoyed them with a 25 watt el84 tube amp. Usher 718 tiny dancer is another nice speaker, a little brighter than lsa but very nice.

Cedar. I have a dedicated feed from my CU and thought my power was pretty clean as well until i found a conditioner that worked. Over bright/thin sound is the predominant character of noisy power. re the Tripp Lite Isobar, it’s quite common to start out with a power block surge protector and then find the sound is better without it. you should try plugging the power cables direct into the wall and just see if it changes anything but i would really encourage you to buy some after market power cables. you will need try some or all of the components with a conditioner to see what works. have fun experimenting! 
I'd suggest you try some vintage bookshelfs ... the KLH 4 or KLH 5 come to mind as having a very accurate midrange, but there are others.  

But before that .... your room dimensions are a square, not generally good for sound unless lots of openings.  Perhaps try some unusual placements or add some sound modifying elements.
mate, you will not go wrong with ZU.
I have the Soul Superflys and they rock, pardon the pun.
Blues is probably 75-80% of my listening choice.I also use Klipschorns and any of the Heritage line from Klipsch will be suitable too.
Possibly mentioned, but didn’t want to troll through all of the replies but are you using a DAC?The Denafrips Ares is an awesome little DAC for blues. Very soulful with excellent bass and I would even go so far as to suggest that you try one with the speakers you already have.
Enjoy the search.

So is the conditioner for the source only? I keep reading that I need to plug the amp into the wall, then hear it needs clean power, which is it? I don't mind spending money on better cables, can you recommend an entry level cable for the PrimaLuna amp?
