Speaker Advice Welcome

Can't comment on either of those speakers, and thus I'll defer to my esteemed HiFi experts.

But, consider auditioning either the Klipsch Heresy IVs or Forte IVs.  Although I know they are not for everyone (to each their own).

They're lively, fun, dynamic, soundstage very well, image very well, and integrate perfectly with Rel subs. I've been told Kef image and soundstage a degree better than those Klipsch speakers... but, going further on imaging specifically will take you to the clinical side.

People refer to Klipsch as being bright.  I've owned Klipsch for 35 years and have no idea what they're talking about (honestly).  I have never viewed them as bright.  If fun, lively, and dynamic equates to bright, then maybe those folks should live under a bridge down by the river.

Turning to your dilemma, I thought I would propose listening to Klipsch because of what you'll learn from the experience.  If you don't like a fun, dynamic speaker, you'll know immediately and can cross it off your list.   Depending upon where you land, it very likely would tell you whether you lean more towards the clinical (Kef) or the warmer (Lintons) presentations. 

BTW, the Klipsch have elements of both within the same speaker (only "elements", but again, none of the Klipsch Heritage line are clinical nor bright...only lively like you're there...with a touch of warmth).

Best of luck with your choices.

I was putting together a Den system about a year ago and auditioned both speakers. I bought the KLH 5’s.  They sound more open and natural for the music I listen to (1970’s to Current Progressive Rock, Classic Rock, Heavy Metal) and remind me of how music sounded as a teenager.  I really like the passive attenuation control that adjusts the mid and high frequency output.  I don’t think you would go wrong with either speaker, but the KLH 5’s just sounded better when playing Gabriel era Genesis, Yes, King Crimson, Dire Straits, Bowie, Led Zep, etc.

I currently run them with an Audio Research SP17 preamp and McIntosh 225 amp.  The turntable is a Rega P3 with a new ND5 cartridge, the streamer is a Bluesound Node, and the CD Transport is a Cambridge CXC with a DacMagic 100.  Great little system.

KLH 5s by a mile.  None of the Linton big cab speakers sound very good for the money you pay.  Bloated, dull and incoherent driver blending.  Including the Dentons which are just awful sounding.   They look nice though....  Seriously.  

For the 3K you are spending I recommend Monitor Audio Silver 3007G 

@avanti1960 have you listened to both?  Just curious?
 

this guy is saying the exact opposite of what  you're saying.¯\_(ツ)_/¯
