I am building a set of 6 mono amp for my stereo active system.
The requirement is all 3 amps should be in the same topology. The power amp for the bass should be capable fo 250RMS, the mid amp should be capable of 100W and the amp for the treble should be capable of 50W.
I am currently thinking about the audioLab 8200M as my treble and mid band amp. and the audiolab 8200mb for powering the bass.
If you have any suggestions, please let me know. The budget of all the amps are USD 10K.

akltamCheck this FO (First One) AB class amps module by Lazy Cat , output power is 160W/8 ohm & 250W/4ohm ,it is very fast CFA ( Current Feedback Amplifier ), very sweet sounding and cost only 88-Euro per module .
Best Regards !

One question - what speakers are you driving and to what levels?
Is brute volume all you need or are you looking for detail?

I am driving a 3 way DIY speaker.
The tweeter is the Scan Beryllium Revelator,
The mid is the Volt VM752
The bass are twin bass drivers per side using Scan 25w/8565.
Thus I am looking for 3 pairs of amp of the same topology with most higher power on the bass, and then the mid and then the tweeter.
So I am looking for 250W on the bass, 100w on the mid and 50W on the tweeter.

Consider a good tube amp to driver the mid and tweeter and a balls to the wall solid state amp for the woofers.
That would simplify your task. As well as an added "cool" factor, besides tubes work sound great in that range.
Thoughts?

Unless your speakers are very insensitive.
Audiolab's house sound is a fairly typical solid state affair with some muscle and clout. But they can sound a bit clinical and shrill.
I would choose the amplification based on how well they compliment the speakers sonically. Wattage is a very limited means of finding great performance/equipment-matching.
If the tweeter gets a 50W amp, it make sense the mid gets a 100W amp. And then the bass to get a 200W amp at least.
In this case, it makes perfect sense to specify the power of an amp for each band of the speaker. Obviously I am looking at 'honest' ratings of the amps.
Also I am looking to get amps of the same topology so that the amps among the tweeter, mid driver and bass can match each other.

The worst thing you can do is buy an amplifier with too little power for your particular speakers to play at the loudness you desire. Therefore, I think the most important factor to begin with should be amplifier power. Too little power is a definite show stopper regardless of how great the amplifier performs in other areas.
To each his own!

It's hard to find transistor power amplification with too little power unless you buy a matchbox amp from China on ebay for $30!
There are some ropey amplifiers out there which claim 250 watts/channel which sound like cheese grater wind-chimes.
When you choose amplification based on how well it compliments your speakers sonically, the issue of enough power is handled by default, because if there wasn't enough power, it wouldn't sound very good at the desired volume level to begin with. The sound would reveal what excessive distortion usually reveals - sonic unpleasantness.
