We should reject hard-to-drive speakers more often

Since my wife doesn't like my speakers but we both love of tube gear, we're keeping our tube gear and now looking for efficient 'enough' speakers. I mean, my amp has 150wpc in pentode mode so what might be the problem? Woofers. But there are efficient speakers with built-in class D amplifiers that release the burden of your fine tube gear playing full range. Let the tube gear focus on the mids and tweets where the majority of the music lives.

Maybe I'll find out one day.

this month's Stereophile has a review of the Heresey speakers, which are super efficient. The reviewer used a coupe flea 2-3 watt amps then used a Parasound 21+ which had more balls and sounded more organic

For clarity ( no pun intended ) it is the Klipsch model Lascala, Revision AL5 that was just reviewed by Stereophile, but it IS part of the Heritage line. Klipsch does have a model called the Heresy, which also has been around a long time, which has also gone through many iterations. My best always, MrD.

It’s funny how them junk infinity’s as some call them

still sound as good or better in some cases then what is being 

produced today at 5 times the cost. Yes the crossovers was 

a pain to work with but back in the early and mid 80’s they was state-of-the-art the art. The IRS beta can go against about any 30,000 dollar speaker made today. And yes you should have to rebuild them now hell they are going on 40 years old. So yes stuff wears out. I own a set of Kappa 9.1 series 2 and I would put them up against any speaker made today under 15,000 dollars. 

I’ve owned many of the aforementioned hard to drive speakers and overall, they could not sound as natural and relaxed as an efficient horn speaker.
