Are you still enjoying this deck? I have one on its way to me. Should have it in a couple of days!

Have you used the auto bias feature? I didn't realize this deck did this until I started looking closer at the manual.

BlazeES - I know what you mean. Many of the ES cassette decks are just rebadged non-es units. For example the KA1ESA is the same as the TC-KE500S. However the WA9ES (which dates from 1995 according to the manual) is a true ES piece. It is the last true TOTL dual deck they made, and the successor to the WR90ES/WR97ES/WR99ES/WR901ES units.

I seem to recall reading somewhere that the TC-WA9ES was the last ES series Cassette Deck that Sony built.
BTW, the s/n of my unit is 7A 801509
Well, the flimsy chassis construction of the WA9ES despite the impressive specs does not convince me that its a true ES unit. I also have a TC-K730ES and there is no comparison. All components from transformers to knobs to feet are on a Elevated Standard on the 730ES.
...but I think it's more a question of what got cost reduced and what the net effect was to performance...
Where does the TC-WR9ES fall in all this? I've kept an eye out for information on it ever since getting one awhile back, but never see or hear anything about it.
