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

Not a real issue.  Why would any thinking audiophile use a high capcitance cable in the first place?
Thinking of Wonder Cable, yes, this is possible. It warms up the sound, and enhances imaging.

The oscillation part though, IMHO this is poor design. First, I don't know of any cable that has more capacitance than an ESL speaker. Second, it is easy to deal with this, and usually is, with an appropriate output snubbing network, or massively over-built output stage like Sander's Sound does.
Appropriate speaker cable should not be high capacitance. 

There is plenty of badly designed equipment around - don’t choose said equipment.
