For the money, there may be no better option, though many would state my Krell DUO 300 XD might sound as good or better.
When I heard the CODA #16 I thought it sounded a lot like my KRELL DUO 175XD. The 175XD cannot go down into 2 Ohm as strongly as the CODA. I heard a bit of that when I had my Thiel CS3.7 speakers and thought the CODA #8 drove them harder.
I liked the Benchmark AHB2 and the KRELL DUO 175XD overall more than the CODA #8 with the Thiel CS3.7. The CODA #16 is sonically a slightly cooler 175XD and slightly warmer AHB2. A real great amp. If I owned the CODA #16 when I had the hard to drive Thiel CS3.7 I am 100% sure it would have been my favorite on the Thiel.
With regards, to the dealer. The fact that he likes the PASS more than the KRELL means he prefers a different sound than me. So I really do not take his opinion to match my tastes. Different strokes. An amp that is warm is really not my personal preference. The KRELL XD does a great job of not going over my warm threshold.
Luckily for me, if needed, I have an ’extra’ KRELL 175XD amp that I can use temporarily with the Blade 2 Meta while I go and listen to the i400.
Walter Schofield and Dave Goodman helped me select the 175XD for the Thiel CS3.7. Very helpful and KRELL also made me a custom power cord for the 175XD.
I have been watching this for a while, but wanted to wait for the i400.
