Classe Audio Amp5

In my quest to find a small yet powerful 5ch amp I have decided on something using Class D technology. Was nearly set on a custom option from either Nord or a new business called KJF Audio.

However, I just came across a used Classe Audio Amp5 that is in my price range. I know this is a brand who has many products considered as "audiophile" and is usually rather expensive. But being a Class D amp, wasn't sure the thoughts on it/impressions.

Also, is it their own proprietary technology or built around something like ICE or Hypex?

also the Amp5 is odd in that it only has XLR connections for channel 1 &2. Channels 3,4, and 5 use RCA

From what I read they closed down in 2017, but was then bought out beginning of 2018 with plans to reopen their Montreal location and re-hire many of their former employees. They were present at CES.

I saw that but that is perfectly fine for my use.

Going from 120 watts to 200 isn't much of a difference. You were looking at 500 watts for the front 3.

What difference do you expect going from 120 to 200?

I suggest you go with the Nord or KJF, that should put an end to upgrading amps.

if you ever get a 4ohm speaker and like to turn it up for movies or music....you probably gonna want more than 200w. my rotel integrated is 200w and I lose about 4db in spl compared to my nad amps bridged(600-1200 watts however nad measures). in my setup thats like 90db to 94db...my focals do well over 100db

I just wasn't sure if the setup/technology/implementation Classe used brought something to the table worthy of paying for.

Another thing I have found while reading about Class D amps, at least at the time of the Amp5 being made (2015), is Dead Band Time and how too large of a time frame can cause noticeable distortion. Being from 2015, the Sigma Amp5 claims to nearly overcome Dead Band Time. How do newer Class D modules like Hypex Ncore and the newest ICEpower's stack up? I tried looking at comprehensive specs but couldn't find the answer.
