A "blind" speaker recommendation based on specs...

I currently have a box-stock Peachtree Nova that I purchased back in April. I purchased a separate unit at the same time and sent it off to Canada for MEGA-MODS! Basically a 5 month/$5k with all the bells, buzzers whistles. Burson op-amps, all new resistors, caps, high-end next-gen WBT jacks/posts, Furutech IEC inlet, new tube, tube base, internal wiring, volatage switching removed, internal shielding et al. The whole enchilada! And yes, I do know there were & are other options out there. Pardon if my choice wouldn't have been "your" 1st choice.

Now, without mentioning names I'm wondering if I should keep my existing speakers which were new in April or at least consider an upgrade I've been researching closely. In order to maintain some semblence of subjectivity I'll keep speaker proper names out of this and list specs only in an effort to keep things honest/objective.

The Nova is a hybrid integrated SS amp/tube preamp with an honest 80wpc into 6 ohms.

My current speakers are high-end (for a bookshelf) on factory stands, 8 ohm with 88db sensitivity. The speakers I'm considering are also bookshelf on their own 200lb stands, vulgarly spendy uber high-end 4 ohm with 87db sensitivity.

Disregarding getting into speaker-to-speaker sound quality, how much harder/hotter is the integrated/hybrid likely to run with the 4 Ohm/87db setup than it does with the 8 Ohm/88db setup? Significant? Dramatic? Negligible?

TIA

Thanks for all the responses/suggestions. I was hoping that given the 4 Ohm speakers would definitely, on occasion, drop below 4 Ohms that by never seeing even moderately loud volumes I could expect a relatively long amp service life.

BTW; 8 Ohm speakers I'm using now are B&W 805 Diamonds and the 4 Ohm upgrade I was considering is the Magico Mini II's but doesn't break my heart to stand pat and save the $30k for some other equally frivolous expenditure.

And thanks for the sole suggestion from one of getting a
"real" amp... that was most helpful! ;-)
