I had a similar view on the JJs - just dull and boring. Not wanting to get into the NOS roundabout, I went the slightly cheaper new manufacture roundabout! I tried a few based on the reviews:
TAD RT001: clean, punchy and brighter. I settled on these in the integrated.
TAD RT093: meaty like the JJs, but a bit brighter. Felt unbalanced to me though, an odd reproduction.
JJ 803S: dull. But get good reviews.
PSVane art series: very clean, balanced and even. Nice, but probably overpriced. Use these in the 25LS.
As ever, depends on equipment and ears, but there are a lot of reviews to get an overall impression.
