I agree with choosing a multichannel amp over the 2200’s. I don’t think you can go wrong with the 990/7125 combo. If you went with the 990/7500 or 7700, that would put a serious dent in your speaker budget. Consider the 990/7125 combo leaves you $2102, 990/7500 $1602 and 990/7700 $1102 for purchasing your L&R mains.

Ultimately choosing speakers is a personal decision, what sounds good to your ears should be the deciding factor. There are of course always budget issues, so finding the balance for what sounds best to you vs. what you can afford is often a challenge. The Martin Logan’s are a fine speaker but very expensive to build a HT system with. B&W speakers may be considered "pricy” from the 700 series upwards, however the 600 series offers excellent quality and sound while still being affordable. If you haven’t already I would give the 600 series a listen (you can put together an HT package together for under $3000… $ 2500 if you already have a sub). Another speaker I would recommend auditioning is Paradigm. The Paradigm studio series is also an excellent speaker. To start your two-channel system you might look to use the Paradigm Studio 100 V.3 or Studio 60 V.3 or the B&W 604S3or 603S. Something to consider anyway.
