There where four sessions, each session comprised the four musicfragments. Thoughts were noted during listening (each apart). Afterwards we discussed the different units and their "sounds". Equipment used is: CyrusDiscmaster, modified CyrusDacmaster (modified analogue part only), pre-amp with Siemens Aa choke-load (Lundahl) Ultra-tone 0.1mF out, power amps with UX171A insterstage coupled (Tamura SS351) to TJ300B Mesh using Plitron OPT's (5K). Interlinks are home-made, silver-foil with cotton braid insulation and speaker cable are PHY's (pure copper/silver plated, cotton insulated).
9762M: This unit sounds "nosy", "tunnel-like".Lots of stage and detail with two faces: sometimes open and cleansounding, other times harsh and "tunnel-like". Also: too much highs, seems like low-end is not coming along woth the highs. Sounds maybe better in a horn or in a enclosure. Sounds a little grey.
Unknown: Same character as 9762M, somewhat more open, more warmth (colour) with better low-end response. Better detail than 9762M. Although at certain times highs seem to be uncontrolled and when a voice drops in, it sounds like phase-inverting. Less dynamic compared to 9762M, very relaxed sounding. Maybe this unit needs more time to break-in..
AD12202: This unit "may not be taken out again of the open baffle". This one has no negative sides... All it does seems to be right. Fast, transparent, extreme pinpointing, large soundstage etc...
9710M: The only 20cm unit in test: This one has a somewhat shifted tone-balance: the lowest base-lines are not audible. Everything is presented clean and precise. Someone even thinks that this unit is best in everything it does. The highs can be at the edge...
Received following e-mail:
The unit in question is also a 9762, of course without the M of the other 9762M you used in your test.

It is a pitty that you couldn't use an AD5200M - the successor of the 9762M, same dimensions, same magnet, same high efficiency, but an amasingly good wideband speaker from the sixties. Philips continued that line towards the AD12202, which was able to handle a much larger power (100W as opposed to 20W) and may well be the best driver ever made by Philips.
