Thiel Owners

Troubleshooting demands that we reduce variables. Battery test is cheap and effective and simplifies the decision tree.

Yes as Tom mentined the room at Thiel was a big room. The amps were the Krell FPB 700CX. A room of that size the bass had plenty of weight with the big Krells. 

I was going to go to the "something being wrong with the speakers" as Tom mentioned but you ruled that out. 

I've played around with a few of the large Class A amps known to drive the Thiel's. When I tried a smaller amp in that same series, it did not deliver like their larger brothers. 

Take the time to work it out and you will be rewarded ten fold. 

I was told that the 25 delivers 1000 watts at 2 ohms confirmed by a guy who worked at classe at the time these were made. They just never officially stated it for whatever reason? So maybe the classe needs a little re cap and new thermal pads installed.

What gear and cabling is in your various Systems?

Happy Listening!

thoft,

Its not really the watts as it is the current to handle a load.

A Pass X260.8 is right at that 1000 watts into 2 ohm load. Switching it out to the X600.8 is a very noticable difference especially in the bottom end.

The best test is to see if you can get a loaner amp to try and compare it to the Classe’. If that does not show improvement then you know you need to look elsewhere in the chain. I'd hang onto the Classe' until you work out whats the solution.
