have the insight, which I used in the system described in the following post prior to the SPP.
The experience I described in the aforementioned post happened with the insight as well but to a lesser degree. Not quit as huge, encompassing stage/effect. Manhattan Transfer Vocals were nice, human sounding. Chuck Mangione Children of Sanchez horn, bass etc joyful, real sounding. I did not enjoy having to open the case to change settings;yucky poo.
Enter the SPP; everything the insight did and so much more. Everything sounds more real, much larger sound stage. Vocals, instruments more defined in space. The more settings, ability to change without opening it, sans the custom knobs, gives me a warm fuzzy.
I enjoyed the insight immensely.
