This is horrible news!  I've known Arnie for many years.  He was one of the first people I met when I got into the high-end business.

He helped me immensely. 

I bet Paul McGowan is devastated.  They were very close.

R.I.P. Arnie and thanks for all the GREAT sounds!!!
By the sound of my Renaissance 90's the man and his crew put their heart and soul into their work. Not only design and build great products, but actually test each unit to ensure it performed as designed.  You will see crossovers with different capacitor values in the same model.  If they didn't test right, they adjusted the values until they were perfect. 
Thanks for all your hard work Arnie. -John
Great story RWD !
man that must have been a hoot
lots of the true grit designers started in a garage
yes Paul is devastated- he posted up a nice tribute and link to a 20 minute interview w Arnie on his email/ blog
catch it !

I remember the 'early' Infinities, and watching/listening to them grow into the 'watermarks' they became.  Even got to own some...*S*

But legends become history...and we get to mark their passing.

RIP, Arnie...and Thanks.

...and thanks for that comment, johnk.  I'll keep that close at hand.... ;)
Another lion of the industry.  My good friend, Bill Legall, has had many of the Infinity IRS models in his home, and we were fortunate enough to enjoy them.

Rest in peace...
