I’m looking for an sleek integrated amp under $15k

How about this Aavik Acoustic U-300 listed here?

What about a Gryphon Diablo 300 with phono module. You’ll probably have enough left over for a decent DAC/Streamer. 

Mola Mola Kula is 15.8k without a DAC and 8k more with a real Tambaqui Dac

destroys all Hegel

destroys Naim that is more midfi

destroys Gryphon

destroys midfi hifi rose

Aavik integrated also good I would demo that as well and see what has better synergy.

destroys anything else under 35-50k

to beat it you need a 41k DartZeal integraded

@rdk777 the Diablo 333 is 25k and not out for USA and DAC is not out anywhere for it and will be 6k putting it in at 31k. I heard a prototype it was marmite because it was not ready for prime time yet. To be determined!

I have never heard the Mola Mola component only their DAC.

I would also consider looking at what vinnie rossi offers.  Good guy and knows his stuff.

Happy Searching.
