A little Patience sometimes pays off! (Kef LS50 content)

yyzsantabarbara,

     Are you opposed to adding a properly positioned sub in your small office?  Even a relatively small sub, if properly positioned in your room to optimize bass performance at your listening seat, can likely provide the improved bass you'd like.
     There're even wireless subs if you're concerned with intrusive cables and wires.  
     To set one up properly, just place the sub at your listening seat, play some music with good and repetitive bass and slowly walk around the perimeter of your room.  Once you find a specific spot where the bass sounds best to you, position the sub at this exact spot.  To verify, sit at your listening seat, play the music again and make sure the bass sounds good to you.  If it does, you're done.  If not, try re-positioning the sub in small increments until it does (always best done with you listening at your seat and a helper moving the sub.).  If having difficulties, you may need to just to begin the procedure again from the beginning.
    Google "small home audio subs" to check out options.  This option will probably be less expensive, too.

yyzsantabarbara,

     Understood.  The Persona 3F look very nice.  They're expensive and look it, very stylish in that blue.  They should deliver better bass response than the LS50s  and seem like a good system match with your Peachtree integrated.  You'll have a complete Canadian system, too.

Best wishes,
  Tim
