I recently purchased a new integrated amplifier. It's a hybrid tube and solid state model. See link below.
I just found out that one pair of speakers that I own are not compatible with this amplifier. See link below.
According to a friend (broadcast engineer) this particular design is well suited to solid state amps but not tube type. This is his response to my inquiry:
"The problem isn't speaker cables, it's the amp's damping factor. This is one area where a solid state amp has the advantage over a tube amp. I see the Castle speakers are ported; I'm guessing the Mirage ones aren't. The damping factor puts the brakes on the cone excursion and a sealed box does the same thing."
I have some Mirage OM 10 speakers that sound great with this. But I am planning to purchase a second A3 and build another system for another room in the house. Thus, I need to find a second set of speakers that will work properly with the Qinpu amp.
Can anyone recommend any Polk speakers that will be compatible with this kind of tube amplifier? I prefer a neutral sounding speaker (not artificially bright like Klipsch) that won't serve up a lot of listener fatigue. I have heard that Polk makes some warm sound speakers and so I am hoping that I can find several models that might work with this amp.
Any suggestions will be appreciated!
