Confused with the VTV vs Buckeye 1ET7040 Amplifiers

[simplywyn]

For me it was ordering a UMIK microphone, downloading REW and borrow a mic-stand. And some reading how to use REW. The measurements were revealing!

That requires me to do a billion things.

Right now I’ve just moved some foams around and it’s much better lol.

That means, this is also false marketing? https://www.apollonaudio.com/apollo...lock-amplifier-purifi-1et7040sa-weiss-op2-bp/

None of these amps can actually hit 950W

Those use a linear supply not the Hypex smps so they may actually be able to reach their rated output into 2 ohms.

Peak vs continuous power output is also a factor in published ratings.
Purifi is as good as it gets. If you want more bass, a sub, two if you can swing it, is the ticket.

 

[Buckeye Amps]

They use the SMPS1200A400, according to their own specifications list on the product page

So basically Buckeye's the only one telling customers what they're really getting

I'm not going to make a blanket statement for all other brands and what they quote, but as far as the 7040SA...if an SMPS1200A400 is the power supply being used, it cannot reach the maximum wattage quoted by Purifi.

I read this on the web site linked above:

"This is how the mono blocks can be described in one sentence and we have accomplished that with using a linear power supply to power the highly acclaimed Weiss OP2-BP Op Amp that is incorporated on our custom input buffer board."

I stopped reading at "linear power supply"....I should have kept reading! You are of course correct.
