After a few years of using the Pod Go Wireless, I switched to the Stadium and to find the same sound sensation that on PA systems often becomes too sharp at the beginning, I had to set a high cut at 4300 Hz. I was quite surprised because with the Pod Go I used the Global EQ like this: Low cut 120 Hz and Hi cut 6300 Hz obtaining a very credible and pleasant sound on the high frequencies. The difference between the two machines left me very perplexed, and even with the hi-cut at 4300 Hz, the Stadium for my ears had something wrong. Then one day I started playing with the input impedances and now finally setting the impedance to 22K I found again that sensation of real sound that I had with the Pod Go and the Hi-cut on the Stadium is now at 6300 Hz. With these settings (impedance 22k, Low-cut 120 Hz 6dB per oct., Hi-cut 6300 Hz 18dB per oct.) I find that the sound is truly beautiful and credible. Even the dynamic response becomes more "true" and the amplifier models respond to the tones in a more realistic way. I emphasize that with the Pod Go I used either a buffer in front or I used it wirelessly therefore with a buffer to overcome the well-known problem of input impedance which, unlike the Stadium, made the duo too opaque.
