Have you used both on bass? What's your opinions on both and which did you prefer?

Something to consider with the FFA - you have two power inputs, i.e. can spread the load across two power sources (albeit with some careful consideration of origin and earthing arrangements) e.g. two 13A plug to powercon on a 32A ring

You’re not usually likely to pop a single (genuine) 13A fuse with even the heaviest music content.

A 13A fuse will pass 20A forever without blowing. A 32A current needs to be applied continuously for well over 6 minutes to pop that same fuse:

From https://www.pat-testing-training.net/articles/fuse-operation-characteristics.php

A Type C or D 20A breaker would trip before a 13A fuse pops. Curves can be found here:
https://www.electricaltechnology.org/2021/07/tripping-curves-circuit-breaker.html

Using two plug tops won't change that. I'd argue that you're more likely to melt the plug top(s) with either amp on a 32A breaker, if your drivers can handle that continuous current - and that's with pure tone signals, not music. The K series can be set with a current limit anywhere between 16A and 32A depending on what breaker is at the other end.

Both amps are quite readily available across the UK, so the sensible option is to hire both and try them out for yourself. Ideally level matched, so make sure the K10 is set to 32dB input voltage gain.

Thanks for the reply I've already tried the k10 had good results. Was really lovely. Not UK based but can probably borrow an FFA from Spain to try. The FFA can be picked up with warranty for a few hundred euro less than a good condition k10 DSP here.

LOL… I have posted this info on this forum several times over the years and been roasted more than once for stating that a 13A fuse will pass 20Amps almost indefinitely…. despite posting the link to the  Pat-test-training article and posting a graph for Bussmann BS 1362 fuse

Yes, just like some simple facts about how speaker (and amp) powers are now calculated somehow doesn't quite register with many people and we still get all these queries on those subjects.

And always referenced to power, not SPL, not quality of build, components, glues etc. A load of a very well known (brand new) 18's failed when left in a truck in the hot sun here for a couple of days. It was classic. Total glue failure!  Ouch

Owned a k10 for a good few years, sounded pretty good but never understood what people were getting at with the 'hollow bass' sound.

Borrowed an FFA and was blown away, much more user friendly (imo) and warmer sound.

Sold the K10 and gone for FFA.. but each to their own

Both running our 1850s at 2ohm, the FFA didn't break a sweat compared to the k10.

However when we powered 4x Element 5 Predators with their reccomended drivers (can't remember which ones) off the k10 it was gut wrenching lol

Also being based in the UK FFA HQ is only a 40 minute drive from us if anything was to break

Thanks for the fuse charts but I'm not really sure how that applies to my comment?

The ability to supply the FFA from two sources is a feature that the K series does not have, and I feel that it's worth calling out

There are many people on here who venture off to the woods with equipment and the option of running from two smaller generators could be of merit (again, consideration to earthing arrangements required)
