Guitar lacking bite, vocal lacking presence

It's a bit confusing as I've always heard that thiels required careful setup as they tended to have a hot top end if not careful.

There is a thread entitled "Thiel Owners" which has been running forever with about 14,000 posts under the "speakers" topic.  One or two of the posters still sell Thiel speaker components and I believe are related to Jim Thiel.  There I believe you will receive additional excellent advice.  It's the place to be.

Are you sure that your tweeters are operating at full steam?

@jetter You are correct that some find the Theil aluminum dome tweeter to be “hot”.  Its frequency balance is extended up to my ears when I was considering both the 2.4 and 3.4 designs.  But, to my ears and others, there is a lack of air on top.  So, some do not like the hot Theil metal dome treble.  Others like me feel the extension that creates the feeling of air is missing.  Bottom line is something is wrong with the system or setup if there is no “bite” as posted by Andy.

The primary message of my post was to let @andy2 know that he would probably obtain the most on point recommendations from the "Thiel Owners" thread, here:https://forum.audiogon.com/discussions/thiel-owners-2?highlight=Thiel%2BOwners .  Dedicated Thiel owners, and people who I believe worked with Jim Thiel and still sell components (if not speakers (?)) and from occasionally visiting the thread seem very generous with their knowledge.

Did you really set up your system right in front of the gas wall furnace

"I also built some of  my speakers" - are these "modified" Thiel CS2.4s?
