Hey guys, 

 

I've read this forum lots and I think it's hands down the best source for HT feedback and information.  I recently started building my home theater system about a year ago.  So far I've got:

 

MartinLogan Motion 40 towers

Marantz NR1603 AVR

Peachtree Audio DAC-IT

Sonos Connect / Roku 3

 

The 1603 is a great reciever and I love the low-profile, but I bought it with AV separates in mind.  I'm currently bi-amping the speakers and for the time being it sounds great, but I've began shopping for an amplifier.  From what I've read it's best to avoid Class D amps, so I've been looking at Class A/B amps.  The problem that I'm coming across is power requirements.  What power ratings should I be looking at?  ML says the speakers should get 20-300, so I feel like peak is probably 300.  I felt like 150-200 (4 ohm stable) range was probably where I should be shopping.

 

Thanks in advance

What is your listening preference?  Movies or more music?  I'm 80% Music, so I'd be looking for an amplifier that is "more musical".

And what sort of measurement is "musicality" and what is a good number for it?

Power requirements can be estimated pretty accurately using a calculator such as this one:

You might want to collect some info about your listening preferences with a SPL meter such as this one:

http://www.ebay.com/itm/271167212819?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

Beside being very attractively priced, it has a peak hold feature that relates to this situation.

There isn't one.  It's all about the ear test.

That makes you a perfect candidate for an upgrade.

Sounds like you are a true audiophile and as such it really isn't worth getting an amp that is lower quality than something like this http://www.audioadvisor.com/Bryston-6B-SST2-300-Watt-Three-Channel-Amplifier/productinfo/BY6BSST2/#.Usl7eX-9KSM
This amp has the reputation of being very musical and airy.

You mean it isn't accurate?

I dunno about audiophile.  I kinda stay away from that term simply because my budget isn't that high.  I'm looking to spend about $1500.
