Near field monitor advice please

Just an additional note.  The Proac, Spendor and ATC options all use soft-dome tweeters.  These can be very pleasing to listen to, but they are not as high resolution as hard dome tweeters.  However, they are more forgiving on bad recordings or source equipment.

The Genelec metal dome tweeter is going to be more picky on good source electronics (i.e. DAC / preamp).  The Adam ribbon is going to be the same, but likely smoother sounding than Genelec metal dome.  I couldn't even begin to give you a "Genelec vs. Adam" opinion.  They are going to be radically different.

A monitor like Genelec 8331a is really designed for mix-down recording engineers with features such as the coaxial mid/tweeter and fully configuration dipswitch EQ - meant to get as flat as possible.  Don't get me wrong, this could be an amazing sounding speaker (I just have never listened to one).  Be aware that this Genelec does use metal dome tweeter (in case you are sensitive to these).  I generally tend to avoid the metal domes after years of listening.  They have a tendency to have a bright edge (due to the metal breakup distortion).

I'm currently using Yamaha HS8 monitors in a very-nearfield scenario.  The speakers are literally only two feet away from my ears.  The tweeters are 3" further away compared to the woofers, but I still love the sound (they are re-capped / upgraded / modified).  The Yamaha HS8 are likely not good enough for what you're looking for.

My next set of monitors will be the Adam A77x (which are kind of larger than normal).  They look like an MTM center channel speaker, but they are actually a 2.5 way design.  Two woofers, both doing bass.  Only one of the woofers is doing midrange and then a ribbon tweeter.  The internal amplifiers are Class D for the woofers, but Class AB for the tweeter (I really like Class AB amps better because they are more open and natural sounding to me).  The entire setup is purely analog.  They are within your budget at $2500 a pair.  There is a separate "A" model and "B" model which use a different woofer for the midrange.  You can swap them around to see which configuration performs better in your situation.

The upper end Adam monitors use all Class D amps and also DSP. That means that the analog signal coming in is converted to digital for full DSP/EQ before being sent to another DAC inside the monitor for conversion back to analog.  It's great if you want DSP for doing EQ / room correction, but I don't think it's going to be as pure and/or transparent as the purely analog "lower end" Adam models.

Not all Genelec use class d amps.

FYI, I never said that Genelec uses Class D amps.  I only describe how Adam does their amp configuration.

If you want nearfield listening use what the pros use who use them day in day out.

djones51 - have you actually sat down and listened extensively to these monitors?  Or are you really just repeating "what the pros use".  The professional mix-down engineers have a completely different requirement and agenda to provide a mix that is pleasing on most variations of consumer stereos.  That does not necessarily mean that their preferred "monitors" would be exactly what an audiophile wants.  It really depends on what the "audiophile" wants.
