Does anyone know if a Cambridge CX81 will sufficiently power B&W 606s2's. Eating terrible pre-amp, amp components purchased from England. Everything I read says need 200 watts or better to adequately power B&W's.

Don't know where you read that, please exactly where you saw this.
B&W themselves suggest 30-120wpc as recommended power from an amplifier.
Certainly have no idea what you mean by ' eating terrible preamp ' etcetera.....
the CX81 will have adequate power.
Please expand ....
Do you own either amp or speakers.?

New here sorry.
I used the crown amphlipher calculator. Before used the standard the 1.5 x min to the stated speaker requirement.
The "eating it" ment I got taken by unscrupulous direct sell junk, $1000 I will never get back.
Currently 606s2's anniversary, turntable Fluance RT84, the amps are IOTA.
Speakers are rated for 140 at 8 oms.

Sounds like that calculator need a recalibrating... Perhaps reading manufacturers recommendations might prove more beneficial.
So why are you interested in a British amplifier like the CX81?
Though I notice your speakers are also British and turntable is Canadian...
All good so far but the Cambridge doesn't have an inbuilt phono stage so maybe not a good choice for your turntable.
Would be interested to hear what direct sell junk you got taken by so other forum members can avoid similar issues.

Was thinking a AB amp would be best particularly since the IOTA SA3 preamp & PA3 power amp were such a disappointment, bi-amped 50 watts each. My experience was horrific, ghosted, half written emails etc. The product is poor, going through a PayPal claim now.
I have a string of probably 50 gmails & text over the last 2 months. It irrates me that I fell into that.
Now just want something I'm sure will power the B&W's but still not sure if will like them, the IOTA equipment does not represent what they can do, hopefully.

So sorry just figuring things out. I posted a separate thread instead of replying. I can repost if necessary.
Used the amphlipher calculator from Crown. It takes the distance, speaker sensitivity, desired listening dB, headspace. Used a dB app to determine listening level.. Seems to very greatly any movement i.e. 1 meter distance, 1db sensitivity, 1 degree headspace. Calculated to 75 amps but the school of thought seem to be 1 1/2 to 2× the base rating. Did I get that wrong?

I am not too sure what volume you intend to listen at but that calculator appears to give strange results. The 75 wpc on its own is a bit high.
Stick to manufacturers recommendation would be my suggestion
