I have some regrets selling...

Ohm F speakers. I needed the money to go to Grad School and got what I paid for them and they were three years old at the time I sold them. They were a great speaker and I have wondered how they would sound with the front end and room I have today. Oh well!

In some ways, I regret dumping a mass market system I had many years ago. If I had it today, I could listen to it from time to time, to remind me that whatever problems my present system has, things could be far worse.

Threshold Stasis 7.0 Amp: A Power House from what I recall listening.

Yes, but learned from it as well. (Mac-ss amp, Supratek, Jas _both preamps.) Thought about selling my ML Aerius i but I can not get over the years of pleasure those stats gave me.
Besides......I still love the way they sound.
