$5000 or under speaker secommendations?


I'm thinking about getting a second, used pair of either bookshelf or full range/floorstanding speakers for my system (currently I have the Avalon Radiants and love them).

Not wanting to spend my child's college tuition on this second pair, I want the best money can get for a pair that would typically list around $3,500-5,000 new. I'm considering the Martin-Logan Aerons or Ascents, Opera Callas, Thiel CS 3.5, and Sonus Faber Electa models, but am wide open to other recommendations.

Anyone care to share their opinions, preferences, favorite picks?

Thanks!

I second the recommendation for used Sonata IIs. I have had mine for a little over a month now and am extremely pleased.

Revelation Audio Mistral S6 with sub6, one of the best combinations out there for under $5000, made my prior watt/puppies 7.1 sound lacking in musicality and easily just as open ... I love that revelator tweeter coupled with a morel midrange driver plus you don't have to worry about bass they offer it in spades if needed (2 isobaric subs with 4 subs/tower powered by their own 150wpc amp with adjustable crossover, gain and phase) try to audition them if you can or go to the Montreal show if that's a possibility, they're usually there ... my desire for the Dynaudio Evidence Temptations stopped after these realtively inexpensive speakers.
Go with Martin Logans. You can get them used at great prices. The panels are incredible. If you want good tight bass go with either the Ascents, Odysseys or higher of course.
just want to put in a good word for Harbeth monitors (the M40 and Super HL5 are actually bigger than your average monitors). they are laid back, smooth, natural, and detailed. not terribly efficient though.
Von Schweikert's have several great speakers in this price range VR4 latest generation (used, new may have went up recently)
