No and no, and know that I use a wide bandwidth ss amp with high capacitance speaker cables.
Would you change your amp selection knowing...?
OK - so this thread was promted by some comments on another thread - not wanting to hijack that thread I created this one...
ISSUE: some high current designed amps have an issue with speaker cables that have a high capacitance.
- the amp can be driven to self destruction because of internal oscilation caused by the high capacitance of the speaker cable
- this does NOT apply to Tube amps - i.e. to my knowledge
The amps I know of that are affected in this way are Ayre, Gryphon and NAIM
- only NAIM warns of this up front AND instruct their dealers to let customers know about it
So why don’t other brands warn about the possibility?
QUESTION:
- would it put you off?
- would you select a different amp if the manufacturer warned of this "issue" up front?
Cheers

^I’m not sure if they still do. When I got mine the RC networks were separate. I’ve since read that some have them directly integrated into the cables. I’m not sure, but I seem to recall that separate RC network replacements were available for $20, but I also seem to recall that some might have received them gratis. Some have even made their own. |
I wonder if it's a matter of the math not matching the measurements, unrecognized variables, or errors of another sort? For your consideration: (sorry, but most of the links no longer seem to work.) The authors suggest that the supplied RC networks values for the MI 2's could be improved upon, perhaps someone might be able to confirm or refute this. Furthermore, I would be most appreciative(!) if instructions for construction of the ideal zobels for the MI 3's could be provided. |
