@regg I replaced the CODA 07x and put in the HPA4 with the same XLR. The gain was a little off so I increased the volume. I am listening to the same album on hi-res that I played earlier on the CODA 07x, Led Zeppelin II.
On the all BM stack there is a bit more detail, such as on the first song. There is also a tiny bit of hardness to the sound that was not there on the CODA 07x.The soundstage also seems a little smaller than with the CODA.
This next observation confuses me. With the all BM stack I feel the single AHB2 is not enough juice for the Thiel CS3.7 (it is pretty good). However, with the CODA 07x I feel the single AHB2 is still lacking a bit of power but the sound itself seems more powerful. Now this is a hard rocking album so the more powerful sounding CODA seems to sound better with the AHB2.
I would not say this is the case all the time. In the past, I had the AHB2 in mono with theHPA4 and the sound was more powerful. I never tested the CODA 07x with AHB2 in mono. I doubt that will happen now that the second AHB2 is my headphone amp for the RAAL SR1a.
Turns out I cannot get a switch on the CODA #8 to select the speaker connectors. So it is the regular #8 I will be getting.
I don’t think I got anything more to add on this.
