Inexpensive Tube Amps

The "where I wound up so far" story: I became enamored of the sound of my Had amp used with a pair of new 93db Sonist Recital 3 speakers until I put my previous Silverline Preludes (supposedly 91db) back in the system just to see how they sounded with the SEP amp. Sold the Recitals as the Preludes sounded more to my tastes, and that got me thinking about efficiency generally which led me to a pair of Klipsch Heresy IIIs. The Heresy IIIs at 99db are perhaps the most efficient 3 way around without getting into large horn loaded boxes, and they are a surprisingly coherent and clear speaker. I say surprisingly because I assumed I was too hip for a silly Klipsch speaker that had been around in some form since the steam power era, and man...these things are great, but need a sub or two. 

Since when is 3.5 W @ 8 ohms, even tube watts, adequate for anything other than quiet background music or super-efficient horn speakers?

Well, efficiency is the key with low watt amps now isn't it. My Omega's are rated at 94.5 and I can assure you they most definitely play loud enough with just 2 watts.

Besides efficiency, it is relative to the volume desired from the listening chair and the music being played. My home made 1 wpc class A amp ( a modified Citation 12 ), drives my Lascalas very well, but 1 or 2 notches higher on my preamp, or playing a song or 2 from Peter Gabriel ( just as an example ), and it runs out of steam. Enjoy ! MrD

Lloyd.  My 6 Ohm Mirage OM 10's are fine with this amp.  5 wpc and with a sensitivity of 91 db I get more than enough sound to hear it 30 feet away even with the volume knob around 11 AM.  In the same room or an adjacent room and I can leave it at 9 AM and will be adequate for listening.
