And as I mentioned, age of your ears makes a difference too and even more so depending on the type of music you listen to.
My 9090DB has the pre-out going to an active crossover which has the sub-out and a line back into the 9090 final amp. The sub out which is also phase controlled (for your room) as well as frequency, drives a David Hafler 500 with the input divided into both channels. This yields about 1000W into a 4 ohm, 15" Rockford Fosgate dual voice coil woofer firing down at the floor. The enclosure is an end table with a granite top and weighs about 200 lbs . It is unadvisable to put a lamp on the table. The main speakers have Scan-speak tweeters and 5 inch mids with a 10" Seas aluminum cone mid-woofer. I built the enclosures and crossovers. This is my office system. And yet, I too avoid audio-pile forums.
This system can also instantly switch the final from the Sansui to a Fisher X-100 tube amp. I did this just to compare the two (tube/SS final) and just left it that way. IS THERE A DIFFERENCE??? Well, yes but it isn't much. A SS to tube pre-amp switch would be fun too and possibly make more difference. Hum - - -
This is not the system for which I have devoted the most effort. That one is another story altogether. These were built at low cost and lots of work.
P.S. Visitors to the radio museum are welcome to check-out the system at the shop, which is better than the one above. Bring a CD/file that you like.
