Heres something you don't see every day....
An SR325i with an RS1/2, GS1k headband. Somewhat rare occurrence, and there were 2 of these here today. I personally have never seen John do this before. It alleviates my only real complaint about the SR325i... headband comfort and padding. The standard 325i headband is much more narrow and has less padding than the thicker ones pictured here.
This one is Jocelyns (from team Berkely-Fi). She was saying she bought it used, and neither her or the seller had any idea this is the Reference/Statement/Professional series headband.
comparison with an RS1....
The 2 near cans are RS1s, the far one is Jocelyns 325i...
I really like the headamp AE-2.
Its relatively new and is based on the AD8397 OP amp.... a very good sounding OP amp when paired with an open, accurate, detailed source. Its got some bass oomph/kick and some nicely forward mids to balance out the spectrum. A good groovy sound signature for portable use IMHO.
Heres something I don't think many members noticed today... Look closely at the graining and texture of the aluminum. Notice how the grains are uniform across the top of the enclosure, front faceplate and back pannel... and extend across the top of the faceplate panel.
What that means is the entire enclosure has to be assembled and buffed/sanded/textured as a complete unit. Then taken apart and serial numbered as a matched set, to go off the anodizing shop. Its a bunch of extra part-matching and re-sorting that no one would want to attempt to implement in a sustaining production process.
Furthermore... if the anodizing shop makes a mistake and needs to scrap the front faceplate, the whole matched set has to be scrapped, or re-worked to grain-match a new faceplate. Anodize coatings are hard and a pain to sand through to the base metal.
Polishing and graining aluminum is very labor intensive, and its an art-form, getting the texture uniformly matched. Airborne aluminum particles are cancer-causing too over long exposure.
The knobs are polished with a metal polishing compound. It gives them a nice smooth "warm" feel to the touch.
My pics dont do them justice... take a close look at these tomorrow everyone. its a very unique looking and GOOD sounding amp. Of course the GS1 is mind boggling too.
Justin, thanks for the detailed discussions. I'll be on the look-out for a metal shop that specializes in polishing. There are some semiconductor tooling suppliers out here in the valley that do this kind of work.
