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.

Agree with pro speaker recommendation.  I’d go ATC for their excellent sound and sealed-box design.  Best of luck. 

Not all Genelec use class d amps. The ones do with their coaxial mid and tweeter. The 80x0 series use AB amps. Neumann uses AB amps in the KH310. If you want nearfield listening use what the pros use who use them day in day out. DSP is becoming a necessity on the newer monitors don't be afraid of it it works wonders. 

I reconfigured my office, and got a used pair of B&W D100i. I have them horizontal on bookshelves, seated ear level, opposite my desk, flanking my monitor for imaging, paired with a self powered sub.

Office never sounded better

After research, I limited my choices to boolshelf 2 way, 6-1/2" driver size, NO PORTS, keep the depth around 11" max for shelves.

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.
