Need Amp Advice


Hey guys,

New member here but music lover for many years.
I am looking to upgrade my amps to get better sound quality and really need some help. I watch movies and listen to music daily. I would say in general, 70/30 (movies 70). I run a 5.1 setup and plan on upgrading to 7.1.4 in the future, but happy with 5.1 at the moment.
When I listen to music I only use the 802's (no sub and no multichannel music).

Currently, my setup is:

Speakers
Main speakers: B&W 802D (first Diamond)
Center: B&W HTM2D
Surrounds: Klipsch
Sub: Klipsch

Pre-amp
Marantz AV8802A

Amps
Emotiva XPA-1 monoblock x2 for the main speakers 
Emotiva XPA-3 Gen 3 for the center and surrounds

The sounds is good, it's actually more than good but I want it to be even better. I have been looking at many used amps (can not afford new ones) and wanted to ask for your opinion on the following that I have considered. I have not heard any of them with my speakers.

1. Classe CM-A600 monoblocks 
2. McIntosh MC501 monoblocks
3. I even looked at the Devialet 200 which was recommended by someone I know
4. Krell?

Do those amps make sense? Am I looking at a noticeable improvement over the Emotivas? I would love to hear from people who know and heard those amps, especially driving 802's.
I am of course open to any other suggestions as well.

Thank you in advance!

Thank you all very much for all your advice.
As it stands right now, I think that my preferred path would be to get 2 Classe CA-M600 (Or CT) and later on add a CP-800 when I can afford it. Problem is I can not find any for sale.

The second option that I am considering is to change direction and buy Devialet 400 (dual-mono). I have been reading rave reviews about those but this product seems so disruptive, that it makes me feel a bit uncertain when it comes to properly setting it up, getting support for it etc. It does, however, provide me with a Pre for stereo in addition to my Marantz, so I don't have to invest in another piece of hardware after getting it.

Would love to hear your thoughts, I am about to make a purchase and want to know everything I can beforehand.

Thank you all and have a great weekend!
I think an integrated amp is an excellent way to go since you need a preamp anyway, and you save the space and the need for another pair of interconnects.  Just make sure it has the juice to make your B&Ws sing. 

I have the Emotiva XPA-5 Gen 3 amp just like yours. I also have the Pass Labs 150 and Pass Labs 150.8 amps. I am completely reworking my AV and Stereo listening room. When the xpa, 150, and 150.8 amps arrived within a few days of each other, I compared the quality of the sound with my Martin Logan Expression ESL13A electrostatic and dynamic hybrid speakers. The source was direct mode with no processing or analogue input from the Yamaha receiver.

3 people listened to a/b comparison between the 3 amps. No one was told what amps were being used. All were above 60 yrs old and not audiophiles. All amps were reviewed with the same results. The Pass Labs were purchased used and the Emotiva was burned in for over 200 hours before tested. We compared musical CD’s only. Rock, Female vocal Jazz, Blues.

These are the differences, heard by all, between the Emotiva and Pass Labs:

Emotiva:        Sharp, clear, very slightly brittle, enjoyable bass and vocals, smaller sound-stage, source location aware.
Pass Labs:      Detailed, emotional, musical, huge sound-stage that made the source invisible. Bass that just felt good to listen to. Voices that felt that they were in the room.
   
We could not consistently and unanimously discern enough difference between the two generations of Pass Labs amps to be statistically relevant. We are not golden eared, just average listening ability for senior citizens.

We are using the Pass Labs for our main front stereo speakers and our elevated front stereo/presence speakers. The Emotiva is for our center speaker and all others.

I hope this helps.
Hey Firstinetallguy,

Thank you for sharing your thoughts. I have not been able to compare my Emotiva to any other amp but I share your observations on the quality of its sound. I can not wait to connect my speakers to a higher quality amp and rediscover my music collection.

I have chosen to go with Devialet 400, just bought one and will get it next week after the holiday. I am expecting miracles, but maybe it's better to lower my expectations to avoid disappointment :-)

I'll keep everyone posted once I get it.

Thank you!
