Back in Rosen's home above Park Avenue, he spelled out, in his typical New York straight-shooter style, why the price was worth it to him.
"I've had lots of systems in my day. I read all the audio magazines every month. The truth is all the specifications are B.S.," he said. "It comes down to, you just need to listen to it, and with this system you just know you are hearing the absolute sound."
Goldmund's Brent Lee explains that Rosen's system is good, but it's not the best the company has to offer.
"Right now he has great equipment and he has been able to start off slowly and grow, but there is some room to improve if he wants to," Lee said. "He has the power to go from Dolby 5.1 to 16 or 32 channels for even more detail in the sound quality."
But for now Rosen is content.
"This is really my fun. I don't have too many bad days, but when I do, I come into this room, listen to some music for an hour and worries just melt away."
