Impossible to say! I made so many changes to my system during the year before I got them sorted out that no comparison to the Snells can be made. I went from a hodge-podge of racking to a new Steve Blinn Super-wide rack that I modified with Herbie's Titanium gliders, Star Sound spikes and Herbies dots to replace the rubbery mini-balls provided by the maker. Then, I was in the right place at the right time when Tweek Geek broke off their distribution deal with Paul Kaplan's Waveform Fidelity and practically gave away his existing inventory of GSIII cables. I also got my phono stage a new set of NOS tubes to replace the factory gold lions, discovered Star Sound platforms, Symposium rollerblocks, upgraded my SACD/CD player from a stock OPPO 95 to a highly modified Sony SACD-1 that finally made digital sound good to me after 30 years of effort. Also, I remodeled the listening room to place the system on a better wall and finally sold the house and started over in an old farmhouse in a smaller but less boxy room.
Now it has been a fine year for system mods as I dialed in the new room. I decided to start here in the smaller digs by reverting back to the Snells and so have not yet tried the Genesis speakers here yet. I have slightly modified the B’s by replacing the front woofers, repairing the surrounds on the midranges, replacing the driver screws with stainless steel (best $2.00 tweak I ever heard), Cardas Patented Binding posts and some aftermarket fuses. I also ditched the spikes in favor of Daedalus Audio’s new Speaker Dids. Every day I think about swapping out the Snells for the far newer and more expensive Genesis just to learn the answer to your question myself. No hurry, though.
Getting back on topic, I did follow Gary Koh’s white paper to set up the Snells here, but it only took a couple of weeks to declare victory and start to just listen to music.
