Follow up on my experience with the B24s after 1 week. Overall a significant step up from the B16 in bass, detail, air, dynamics and soundstage. However, I am finding a puzzling issue with the B24's that perhaps someone could provide some insight on. When I have the B24 connected from the DAC and streamer into the DigiBuss and Digibuss into the outlet, the sound has too much glare to it. Listening fatigue sets in quickly. The initial impressions with this combination is great. Bass is deeper and everything has much more detail and air. It sounds incredible for about 2 minutes then the mids and high become fatiguing. Using a B16 from the outlet to the DigiBuss removes the glare and everything becomes very listenable but with the loss of the added bass and detail and air. Just not nearly as exciting, interesting and engaging.
The current configuration that sounds best is the B24s on the DAC and streamer, using the 3rd B24 from the outlet to the UberBuss which powers my Emotiva mono blocks via B16's. I have tried using the B24 on the amps and UberBuss but that also added too much glare and didn't sound quite as good as the DAC, streamer, DigiBuss combo.
I wonder if my Emotiva amps may be the weak link in the system and are being exposed by the B24s when used in series on the front end of the system. They have been great amps and have done an excellent jobs driving my Maggies so far but given the quality level of the rest of the system perhaps it is time to upgrade them.
I wonder if using B24's in series from the outlet may be amplifying the deficiencies of my system too much? Any thoughts on this would be appreciated.
