I traded my REF5 for an Anniversary REF40 today. It took a couple months to get it but WOW it sure was worth the wait. Right out of the box with 0 hours it sounds better than my REF5. Soundstage deeper/wider, Bass tighter, highs smoother. Instruments startle me at times... I am sure with break-in time it wil only get better. I asked my wife to sit down to see if she could tell the differece. She said she can't explain it but it sounds better (she then described a wider sound stage and smoother sound). The rest of my system is EMM Labs DAC2/TDS1, Lamm 1.2s, Sasha's and REL G1 Sub.
