gthack, It’s the cable manufacturer that has raised
the question. I’m working on obtaining more information. I’m calling Totem Acoustics this a.m.
for clarification.
Thanks, just seems a weird question. Could they tell you an acceptable slew rate from their perspective?
Not weird in that it has no effect, but weird in that it isn’t a commonly published spec of any amplifier, as far as I know anyway. And unless they can tell you what a “good” value was, I wonder why they even need to know.
I remember that the SN3 and XS3 both improved over their predecessors in terms of a doubling of slew rate, but don’t recall any numbers ever being mentioned.
gthack, Thanks for the follow-up. Some manufacturers do list the Slew Rate and damping factor on their products. Anthem Audio does. There STR Integrated shows a Slew Rate 30 V/μs
and a Damping Factor (20 Hz - 1 kH 330. I’m still attempting to find the Naim specs. I did locate this…“Most amplifiers (even the cheap ones) should have a slew rate above 6.3 V/µs. The seemingly high slew rates of most amplifiers are simply good engineering. Having a slew rate that yields a maximum frequency well above the audible range will pretty much eliminate any potential errors and unwanted distortion whatsoever…”

One of the improvements in the SN3, over the 2, was a doubling of the slew rate. I’m sure @110dB could tell you the exact figure.

I once asked the guy working at the local fish and chip shop what is his slew rate.
He said “Yes, I’ve got my skates on”

Hi @Gracie.1 ,
I tend to pop on the forum in the evenings. If you message a question I’ll do my best to answer. I hope to be free around 10pm this evening.
FYI We do not publish slew rates (and many other technical measurements).
I see you talk about another amplifier above. The SN will do the same. Technically that is enough speed to drive a 70W amplifier to 7x higher frequency that can be heard.
…however the SN pre-amp section filters ultra sonic frequencies and the slew rate limit cannot be hit. (to measure SR at Naim we remove all input filters).
Best

Greetings Steve - Thank you for the response and technical information. I feel you along with the other forms members have sufficiently answered my query. Armed with this new information I’ll continue my discussion with the cable manufacturer.

Which cable are you looking to replace Gracie?
Wow!
