@Alan March, I've seen over the years that having an even horizontal dispersion is one of the critical sound parameters in a loudspeaker, which makes ...

Will the Ukkonen be upgraded to the Purifi tweeter? Its directivity is awesome.

When is the release date? I believe you said they are ready to order on Facebook?

A pipe organ and classical piano can reach down to 16.4Hz, with custom organ pipes designed to reach 8Hz! Only turntables are designed to mitigate inf...

I was also curious about the differences between the P482 spectral plot above andone for the P801 below: Is the difference in the 1 KHz harmonics (...

I stand corrected...Thanks! Now, the -115dB spec removes the effect of noisy sources, correct? You measure the amp's noise floor (inputs shorted), th...
