The Rega Elicit Mk5 is a 2000 quid amp, these Elacs are about 4500 quid new. So in your esteemed opinion the Rega is not worth buying? They highlight it as a feature upfront 'powerful 105 W per channel into 8 Ω loads (127 W into 6 Ω)'. Rega is also upfront in the manual and website that the amp will not endure 4ohm rated speakers for prolonged periods.
It's clear that the Rega is not a powerhouse like say a Hegel would be. But they're upfront about it.
A Hegel H95 is 1500 quid, with 60w/8ohm.
Hegel H120 as 2225 quid with 75w/8ohm.
The Hegel 190v that davidf suggests is 3250 quid. And all Hegel integrateds come with ethernet streaming onboard.
It's all a matter of price and matching really. And I remind you again - this Elac is a 4OHM RATED speaker, that dips to 3.6OHM, so play some EDM and it's not going to take a lot to go down there.
Then there are some speakers that are extremely power hungry regardless of price - I refer you to the $1500
Emotiva Airmotiv XT2. These need Emotiva's own amps if you're going to maintain cost/value/matching ratio. And Emotiva themselves acknowledged this. Watch Andrew Robinson's review of this speaker.
Additionally, Elac and others should publish honest specs like Monitor Audio do - some of their Silver series amps officially require at least 60w/8ohm amps.
To recommend a 40w minimum for this speaker is plainly dishonest.
