Accuphase E-450 or Accuphase E-550


My speakers are Focal Electra 936 and I am using them with Accuphase E-213 in a room 19*22*9. and I feel I need more power than the 213 has.
I like to listen mostly to Rock and Folk.
Which amp. will be the better route: the E-450 or the E-550?
Will I get a substantial improvement over the 213 in bort amps?
I can not audition those amps.
Since I like the Accuphase 213, I think the best thing is to stick with Accuphase.
Do both amps will have enough power for the Focal Utopia Series(hope to upgrade in the futue) .
Your opinion please.

Thank you.
My Speakers are 8 Ohms, but drops to 3.2 Ohms at low frequency.
Did you find the 408 much better than the 213, other than the extra power?
Honestly the 408 is a better unit it has slightly faster deeper bass and overall sound is improved but it is more of a subtle change than dramatic one.

Either the 450 or 550 should be an improvement over the 408 and 213.
Do you think the 450 is significantly better than the 408?

You make me think again if the large extra cost for the 450 or 550 is justifying the replacement of the 213...
the E450 and the E550 are both better than the E408, E213.
In terms of how much better ? its hard to quantify as the E408 is no slouch, the E213 is no slouch either.
the E550 is purer, more detailed than the E450. the E550 is also more transparent but the e450 is more fuller sounding than the E550.
With your JM lab either the E550 or the E450 can drive them easily. Its just now a matter of preference.
Either way, you can't go wrong!
