Wow Norseman, good find! I'm somewhat surprised that they have an adjustible gain with the option to actually increase it above THX level, but there you go, assuming makes an ass out of... well you get the point!
Anyway, that would make the A31 a perfect fit for the lower level signals coming out of AVR pre outs.

They even mention AVR receivers as part of their target market - showing (with a high end product) that ti can indeed be done. Emo 'gets it' with their XPA series set at a high gain for just this reason - smart. (I just wish Emo's new XPR series had adjustable gain - like the high end Parasound A31 - but they're fixed at 29db). Maybe a later version of the same thing? Ah well,...might have to stick with the XPA's as my option, or get a pre-pro, and enlarge my amplifier cabinet & fan! |

Hey people, new XPA=5 G3 owner, and wanted to revive this thread.
I have Yamaha RX-A2030 and the specs show pre-out @ 1.2v and the XPA shows input @ 1.5v w/ only a 29db gain, different than someone posted for one of the earlier gen XPAs.
I love the nicer sound of the XPA, but being that is in 5ch mode should have a wealth of overhead over the Yamaha into 5ch, prob way lower than their stated 155. I noticed fairly easily that -33db(where I normally had it for general TV) on the XPA is distinctly lower volume than the Yamaha at same.
I have re-run YPAO. So I am thinking it's due to the 1.2v on the pre-outs not fulfilling the 1.5v on the XPA?
Now, the Yamaha is eventually going to be replaced most likely by the XMC-1 later this year (gotta spread the $$$ out), but wanted to see what the group thinks.

I wouldn't put anything into the difference in the volume indicator, just enjoy the gear! Im running a Yamaha 3020 with a set of XPR-1's and a XPA-5 and it all sounds great! |

As pointed out previously, the issue with lower voltage output on receivers was noted by Emotiva and somewhat mitigated by the higher gain on the Gen 1 power amps (32 db versus 29 db on later generations). The lower receiver output in combination with inefficient and/or difficult to drive speakers was not uncommon. Since your speakers are far from inefficient I wouldn't be at all concerned. Don't worry about where the volume is, just sit back, relax and enjoy the sound.
An observation, it is common for cleaner/clearer sound to sound quieter, in contrast to distorted and overall "dirty" sound being often perceived as louder.
Cheers
Gary
