Help me spec n class A AMP, power calculation 85dB @ 1W @ 1metre

I was playing few pieces and recoding dB levels on my phone. After playing few tracks I see some parts of music sustains at 88db and peaks at 96db. I do like to hear music at this level for short periods of time. 

I am using the following calculator: https://geoffthegreygeek.com/calculator-amp-speaker-spl/

Sitting at 10 feet away from speakers I see the following numbers:

Assumption amplifier headroom of 1.5 dB, 10 feet distance

For 88db 1 Watt + 14.2 dB requires an amplifier power of 26 Watts
For 96db 1 Watt + 22.2 dB requires an amplifier power of 165 Watts

For 102db (room SPL losses) 1 Watt + 28.2 dB requires an amplifier power of 658 Watts (Ridiculous?)

It would be great if I can go get a class A mono blocks that can do sustained 200 Watts for each speaker @ 8ohm/6ohm and call it day but I got no dough for that.

How do I spec for a good amp(and may be integrated). I would like something that can sustain 35-50 Watts for class A and have reserves for peak of 200 Watts.

I do not need continuous 200w class A. I am looking for continuous 35w to 50w class A but the amp needs to supply the transient load of 200w. I have no idea how amps work. If the 50w to 150w swing would mean engaging class B then it is fine by me. Tube amps seem to not able to manage the peaks(this is my understanding), may be this is incorrect.

Where do I find specification that 60.8 can handle such peaks?

I am going to try out Line Magnetic 508ia. Will update the thread on how they sound with my efficient speakers now and when I change my speakers to less efficient ones.

Find a Luxman M800.

60 watts per channel into 8 ohms is the Class A power rating taking at nearly non-existent distortion. This doubles all the way down to a maximum of 480 into 1 ohm. Actual power, according to Stereophile, is 160x160 into 8 ohms, 280x280 into 4 with a maximum of 480 into 2.

Yes a used M800 seems great, there are concerns with heat issues. I think an SS that can go up-to 100 watts class A and is reasonably priced is Coda 15.5.
