Inexpensive Tube Amps

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.

Look at YouTube before buying nobsound. Guy takes apart his hybrid tube/SS amp to discover the tube section is fake!  The transformer covers are empty!  

If Yaqin is still on your list, look up the Yaqin group on Facebook. They have knowledge, own the products, and there is a thriving subset of them that do modifications, not just tube rolling. 

I have a couple of low power integrated tube amps, one at home and one at work and have tried them with speakers ranging from my Martin Logans @ 89dB/4ohm to my horn-loaded single drivers @ 95dB/8ohms and a couple of other speakers like Vandersteen 2Ci, Def Tech BP20, etc., in between. You can make music and hear it at a decent volume but playing loud is very different from hearing the recorded dynamics of the instruments, vocals not so much. Try playing an orchestral or a rock track at moderate listening levels and you'll get the point. Even a simple jazz trio will lack the dynamics when the power is not adequate for the target speakers. Playing loud is easy - think a $50 boombox, recreating the music dynamics is a different story.
