Rick, Some DSP based receivers are capable of producing great audio. Consider that CD audio is an implementation of DSP. How close to CD quality any practical receiver can come depends on the sampling rates and the number of bits in the A-D and D-A conversions.
Inexpensive amplified speakers can sound bad, although some sound quite good. I would suggest using unamplified speakers with the K3 - I was able to pick up some old RS Optimus speakers and those are currently on my K3. I have also driven a good quality stereo receiver equipped with large stereo speakers - the K3 sounds good within the restrictions imposed by the highest frequency that the K3 audio will go - 4 kHz. You may be trying to straighten out a deficient speaker response with the K3 RX-EQ. I run my K3 with all the EQ settings at zero. Many speakers that are just speakers in a box (usually with an open back) will have many irritating peaks in their response curve. I prefer small Hi-Fi speakers over any of the speakers normally found with ham gear. Since Brian has suggested - yes, I wear hearing aids, but I normally listen with the response set for a flat response without noise reduction - my audiologist set up a special "music" program for me. 73, Don W3FPR On 10/4/2010 9:16 AM, Rick Stealey wrote: > Over on qth.com in the forums area (the "Talk" sub-forum) is a discussion > called "A sad thing happened > on the way to a more perfect receiver."
