@mrpsync I was using the Topping pre90 for 2 to 3 weeks straight on my floor standers which were driven by the AHB2 monos. It sounded awesome. I do not miss the HPA4 since the Topping pre90 sounds like it. I may have mentioned it on this thread that the HPA4 has way more useful features than the Topping pre90. The pre90 is really bare bones but that is all I need.
Today I have the CODA 07x back in the mix and it is also amazing. Every time I switch preamps I tend to like the new one more. Which is a good reason to keep both.
My CODA #8 is finally built and is being burnt in at CODA this weekend. It will ship on Monday. I had SpeakON speaker connections added to the #8 to play with my Audience FrontRow cable which is used by the AHB2 SpeakON terminal. The SpeakON’s added some delay to my amp delivery.
I use my DAC3B regularly because I find it a bit more detailed than the Gustard. I definitely tested this out a few days ago with my RAAL SR1a. I love both DACs and have come to appreciate the DAC3B even more now.
I always prefer a preamp for my DACs. I have not spent mega bucks on DACs so I do not know if other DACs have better preamp capabilities, but the DACs I have listened to have benefited with a preamp.
One of the top 10 DACs these guys ever measured.
