I got nothing against coda but yysantabarbara had the coda integrated you mention, had the krell 300i at same time, ..... and sold the coda. He kept if for only a couple of months. ymmv.I now have the CODA 07x preamp + CODA #8. I sold the CODA CSiB and kept the KRELL because the KRELL had more features that I could use, internal DAC, HDMI, etc.
People are saying the CSiB is very close in sound to the CODA separates. On my power hungry Thiel CS3.7 I find the separates are much better than the CSiB. In fact, this is the best sound I ever got from these very hard to drive speakers.
The CODA separates sound like a mix of the KRELL K-300i and the Benchmark AHB2. Very detailed, smooth, "wet", and powerful. I have the AHB2 also connected to the CODA 07x preamp (it has 2 sets of XLR outputs) and use them for RAAL SR1a headphones. The CODA and AHB2 are a great pairing with the proper matching speaker. The Thiels are too power hungry for AHB2 in stereo and mono. It is not a bad pairing just not the best.
