@ricky64 I’ve ALMOST followed your path, just recently. I too have a Tambaqui. And with my new Audiovector R6 Arrete speakers, I actually now feel that the Diablo 300 has a touch too much bass and that touch of darkness - the same qualities that I felt really complemented my last speakers (B&W 803 D2). Compared to the B&W’s my Audiovectors are more warm and relaxed sounding, but detailed with a lot of bass. The upper mids and treble are not accentuated like they were with the B&W’s which had far less bass.
So with this change, I am looking for a touch more neutrality than I have now, and not the Diablo sound anymore (it’s not as extreme as I’m making it sound and in fact it pairs with many modern speakers extremely well). A contact told me the Gryphon distributor told him that the 333 still has that Diablo 300 darkness but is now a bit closer to neutral like the Apex and Essence.
With that info and with my new warmer sounding speakers, I have an Essence stereo amp on the way. And since I like my Tambaqui but wanted the advantage of an analog preamp without adding another box, I have a Makua on the way with a Tambaqui inside it.
It’s a gamble as I now will have three very neutral components across the Essence amp, Makua, and embedded Tambaqui. But I’m hoping this will be a good match for my slightly warm and full-bodied Audiovector speakers (at least in comparison to the B&W’s). I know for sure this combo will not be bright sounding as the Makua and Tambaqui have that hint of liquid smoothness while being neutral and detailed, but I also know this combo would not have worked AT ALL with the B&W’s!
Despite the high cost, I am okay if it doesn’t work out - I would likely sell and “fall back” to a Diablo 333. But I’m hopeful everything will work out!
Interesting comment about Gryphon Pre’s. Any reference on this comments or is this more a word of mouth thing? I hadn’t heard this before.
Also @ricky64 , which speakers and preamp do you have?
