Lynx amplifier 3.0

the thread about LYNX 3.0 is still HOT

Great project but the thread-starter asked for ~50Wrms amplifier project. Lynx is rated 150...300Wrms.

I'd rather suggest Smyasym as AndrewT did.

A third vote for the Symasym.

so many options! whew!

The crew (MikeB the designer, and the others) in the Symasym thread are looking really kind and helpful. I'm sure they'll help you!

Official LYNX Power Amp builder’s thread

I know this amp maybe "over power". for you

The Design
Let me start by pointing out, that LYNX project from the beginning in 2002 had only one goal!
To create a rock-solid and powerful sonic Power Amplifier like those used in studio's.........
So if you are fond of the deceased mighty and "muscular" power amps from Phase Linear, SAE, GAS, Dynaco
and similar ones, and if you like listening to live recorded LP's and CD's, you may be intrigued by this project
as the result is very close to those.

Components
Components shown in the schematics are only suggestions. The circuit has shown good characteristics and
produced good and clear sound when build with very low cost components. So with this circuit you have the
possibility to either build a low cost dynamic Power Amplifier or a Studio Class Power Amplifier.

that's what i get in the homepage

So it looks like I might need a higher power amplifier like the Lynx after all...The monitors that I am building are 90dB D'Appolito styled MTM's. Any other suggestions for a studio monitoring 250W - 300W amplifier thats well documented and easy to source?

Hi,
I don't think the consensus is suggesting that you need 250W to 300W for your 90db/W/m speakers.
I would aim for 100W to 150W for the levels I listen at and still ensure 20db headroom for the occasional transient peaks.
You may find that as little as 50W will satisfy 95% of your listening needs.
You have to decide if you need 3db more or 7db more.

audio_moksha · 13th April 2008, 07:24 PM

Yes you are correct AndrewT, I guess 250W is overkill. I was looking for about 20dB to 24dB headroom so I stand corrected that about 100W - 150W would be adequate. One option is the Lynx 3.0 adapted for about 150W.

Hi Moksha,
Have a look at RMI-FC100 amp by roender in the threads here, very accurate & with powerfull bass. Its a tad more complicated than others here but youll be very hard pressed to find a better sounding class AB amp here.
