Oh. Sorry. That’s what I meant. I owned RAAL ribbons and loved them. Anyways to answer the other question. I own the SX6300-R.
I believe those have the Scanspeak tweeter - same as my 61lse and T1/R's.
Before I committed to the T1/R's I wanted to revisit my 61lse's because they use the same drivers (just not so many)
When I compared my EMP 41B, I was surprised that I liked the "extension" of its cheaper tweeter better! Certainly, the detail of the Scanspeak is the winner, but the EMP had the right amount of shine "up top" for a trumpet!
After talking with RBH, they said the cheaper tweeter did offer a bit more up top.
I have found that using the EQ on my AVR, adding 1.5dB at 16,000Hz makes it work out just about perfect for my ear. You may not have the same preferences, but you might try it to see if you like it better!
Note: At 60 years old, I know I cannot hear 16kHz. When I tested at 55, I could barely detect 14kHz and I don't know how much I may have deteriorated since then. I don't know how wide the EQ bands are for the EQ in my Denon, but it is a little surprising that adding 1.5dB at 16kHz would make such an important difference for me!
Edit: Maybe it should not be so surprising since the next adjustment below 16kHz is 8kHz, so I might guess the 16kHz EQ is still pretty strong down to ~11kHz.
