Concert Experience for $5k?

Maybe t-bon3 doesn't have as much "horsepower" as he thought, huh Al?

John (Jmcgrogan2), as you probably realize but others may not, it’s not a matter of horsepower (i.e., watts). It’s a matter of the effects of amplifier output impedance on tonality, resulting from the interaction of that output impedance with the variations of the speaker’s impedance over the frequency range.

BTW, there are of course quite a few speakers having relatively flat impedance curves, as well as relatively high sensitivity, that I would expect to be great matches for this amp. Including the Daedalus speakers I use, and I believe also models from Coincident, Tannoy, and others. But I have no specific suggestions to offer that I feel confident would provide the sonic character the OP is looking for (I am mostly a classical music listener, not a rock concert-goer), and that would also meet his price point.

Best regards,

VanL Quartettes  from Van L Speakerworks (chicago) fit right in your price range and outperform speakers at a much higher price point.   These spekers returned many of us to the joy of the music ... 

Go try the Zu. They have many models, one of them might suit you. Regardless of the model, you will get that "live concert " experience. I own a pair of Zu Omen Def because I was exactly searching for that "live " effect and I'm more than happy!

Given that you have a very specific goal (and you know what you want to achieve), you should try to audition any speaker "at home." Many manufacturers such as Zu now offer 30-60 day in-home trial periods.
