Arietta
a question to SKYLAB - do you have experiance listenning arietta/cantate with grado (225)?
would it be a good match for the 32ohm impedence grado (enough current)?
your opinion about the synergy (I'm a metalhead)?
can cantate handle lower impedence better than the arietta?
Thanks

I have no experience with Grados and these Meier amps, but they both handles the 25 ohm Denon D5000 very well.

My Grado listening indicates that while I luv Meier amps with several of my 'phones - I did not like them paired with Grado.......a sidelight -right now using an ASL amp w/NOS tubes for Joe Grado HP-2 and a pair of Alessandro MS Pro.....prefer one set of tubes with them, but my Beyer dt880/600 were better with another tube pairing in that amp (IMO).......Plugged the Grado's into an HA-2 and again, no cigar for that mating.

Thanks for the kind words. I'm sorry that I cannot post the pics you seek - I no longer have the Opera since I have gone all tube

yawn...opamp follow by buffer...how is this better than PPAV2 or M3?
I think designers who use opamps are just lazy; and those who use off-the-shelf buffer instead of building their own FET/JFET driving stage are super lazy!
opamps and off-the-shelf drivers should ONLY be used in gain/driver stage where cost (think cheap DVD players) and temp is a factor.
IMO Opera is a major ripoff compared to M^3 wrt to audio performance only.

But does laziness produce worse sound, or just moral indignation among bored audiophiles looking to stir up trouble?

I was capable of telling all the thing from Aria by first 5 minutes listen. My Little dot MK3 can even beat it in most of espects. As you said that you wouldn't sell the old one for Cantate. But why?

Sorry for the confusing state. I mean, if Cantate is better than Aria in every espect mentioned above why still keep Aria rather than buying a Cantate instead of. Is there anything which Aria has attractive?

I didn't keep the Aria - I sold it and kept the Cantate (for a while, although I now use only tube amps).

Oh wow, that was you. Well, if your nickname is indicative of your taste in music I think you will really enjoy you purchase. Congrats.
