Please tell me.

OK, so I recently got my OLD Harmon Kardon back. It's a PM 655 VXI (20 years old). I currently own a Bryston 4b SST... brand new (a 300/W monster). Why does the HK sound better??? It is SO warm and the bass is sweeter. Reminds me of the Krell KSA 150 I use to own. I can't believe HOW good it sounds on my dyns. WHY????? Is this really as good as it sounds to me????? I'm having a hard time justifying that I spent $2400 on my Bryston when I like the way my OLD HK sounds better. I realize the Bryston is "accurate" and less "colored" but it does not have the sweet warm sound that the HK does... tube like. I'm freaking out on the sound of this unit. Does anyone know anything about it? Please advise.
