I should start off on the proper foot, but I feel somewhat compelled to weigh in on what I am observing here.
It would appear that this forum is dominated by a rather conceited lot, possessing very little knowledge or common sense regarding the audio arts. Perhaps you find yourselves entertaining, in a Jerry Springer kind of way. Its not too far of a stretch to imagine that you have precious little experience with the equipment you choose to lash out at with your thinly veiled criticisms.
Ah, the SET must suffer from compression. My, my. Look at all the funds wasted by recording studios on compressor limiters, when a simple 2A3 amplifier could so easily be fitted for this purpose. And at a rather substantial cost savings, I might add.
If indeed you are able to discern effects similar to compression whilst listening to a SET amplifier, you are exceeding the capabilities of the device. What you are in fact hearing are the effects of clipping. This being the case, your listening habits necessitate a more powerful amplifier, as the common sense limiter has failed to actuate.
Microdynamics and driver excursion are inversely proportional.
For those of you carping about accurate music reproduction, one could only speculate as to the horrific sound that you surely consider accurate. A Klipschorn driven to high sound levels is emitting significantly more distortion. Combined with the reflected energy contained within the room boundaries, and the natural effects of cancellation, you have quite a cacophony. Ah, you have indeed created the club sound in your home. You should be very proud of how you have managed to reduce a superbly engineered product to a level equal to industrial amplification.
Being someone whom earns their worth with my ears, I prefer a similar sound in my home and in my control room. Whilst I consider myself fortunate to own a pair of classic Klipschorns, I do not feel compelled to abuse them, or myself.
Although this fact is certain to be lost on you Power Rangers, it is the owner of the small SET amplifier whom has truly come to appreciate high fidelity sound. Something to ponder as you twiddle the pots on your preamplifiers, undoubtedly named after a pie filling. And of course, whilst listening to selections garnered from the uncompressed music aisle of the record store.
You may now resume your chortling and back slapping. I hope my use of punctuation has not offended the more unstable amongst you. If your neighbors dog starts giving off about hunting me down, please seek professional help.
