@tattooedtrackman ;
I do like the upgrade for $3500 as i was honored with quoted price from last year but was unable to send the unit in that time., Ok about difference in SE, compared to Ref 6, i find floor/ noise is low, mid range and highs are cleaner .Ref 6, sounds little cooler toned than SE; I mostly listen to vocal and Jazz, so i had really liked ref 6. for years ,with up grade i kind of get used to it. if you like warmer sound with SE upgrade, get ready to invest in quality cables, power cords like Cardas cables.
I am still holding out on phono3 and amp upgrades until Dust settles and I can get convinced it is worth $ 5000 upgrade for each component.
I do have alternated warm sounding system hooked to my Focal Scala V2 with AQ cables Conrad Johnson A27 amp and ART 88 preamp with PST/DAC-mkII and MT5 TT.
Hope it make sense and give you comfort in making hard decision. that is not easy in this case.
