Are you able to do home trials of some Paradigm offerings? Compared to other center speakers I have used, I like my Paradigm center speakers the best in term of speech clarity. Mine are from Studio and Signature series and already discontinued. But current offerings should behave similar.
I have similar experience using a transparent preamp instead of using my DAC in preamp mode. I was told using my DAC as preamp is not optimal as it is lossy. So you are not alone in experiencing improvements once moving away from DAC preamp mode.
No. My first was a well used beater. Often had problems starting. Can't even afford one without help of my wife. Can barely afford rent and food then.
How about you?
Instead of keep arguing about why someone "can't", how about thinking about how anyone "can"? This is the original purpose...
Nice, if you can do this consistently over long term with play money, why not.
I may look into this after I retire. Hopefully I won't end up like my uncle who loss all his retirement funds due to options.....
Hi @pma, regarding your post in https://www.audiosciencereview.com/forum/index.php?threads/class-a-vs-ab-do-they-really-sound-different.18415/post-910198 for A21, was it measured with xlr in? Did you do RCA in?
What speakers did you use to check the hum?
