Used or on sale Revels are hard to beat. At their retail prices there are options just as good (more different than better).
I have never heard monitor audio but owned the 228be before moving onto the JBL 4367. The 228be sounds almost identical to the 226be but the 228be will probably play louder.
The Revel has a commit no sin type of sound. They sound “perfect” with wide dispersion, smooth response that drop by 5db in room from 100hz to 20khz. Really nice sounding… but they really lack bass extension. I high-passed my revels at 60hz to subs and they sounded amazing that way. With the sub/speaker combo I enjoyed the system as well as any box speaker ever. Without subs I would not be happy with revel as bass is high on my list of needs.
you mention mid detail, I would say the revel mid detail is on pare with Focal Sopra line, maybe a touch more detailed than sonus Faber Olympica III, a bit less detailed than the tipped up mids of the B&W 802D4 and very close to the detail of my JBL 4367. The highs are typical highend beryllium sounding, very good and I really enjoyed the highs until I bought my JBL which are on another level. If you want to read my opinion on Revel vs JBL you can find my thread about the JBLs under my profile.
if you have not watched the YouTube review of the 226b from Erin’s audio corner you should. It is a good review and I pretty much agree with it 100% very detailed measurements too.
