Thank you so very much! I was amazed at how quickly you were able to figure this out, especially since the screenshots weren't all that good.
I will also check out the other Art Pepper works you have suggested.
The back-story on the fabulous apartment is that Bosch makes some money from a movie that was made based on him. So he is able to splurge and buy that apartment. He otherwise lives a fairly ordinary non-flashy life. It really is a well made series - and definitely worth watching if you like police/detective series. In the series, he also talks passionately about jazz and music, especially when he tries to educate his daughter on jazz and good music, which is why I was so interested in knowing what the system was. It is not often that TV producers or script writers pay this much attention to detail when it comes to an audio setup. They normally throw in a fancy looking speaker to make the set look "cool". And I also appreciated that even with the bad room acoustics, at least the speakers weren't placed right against the wall as is normally the case.
Thanks once again,
Arun
