On amps: after a sequence of other amps, I landed on the Eddie Current Aficionado (Af) as a great match to my music, headphones, and subjective taste. When I started spending substantial time in a second location, I was lucky to get a second used Af, but I started also to investigate other 2A3-based amps, and after many conversations on various forums, I decided on the Stellaris Special.
On DACs: I own a Spring 2 KTE already, which I prefer to the Sonnet Morpheus I have at the other location, even though the Morpheus has quite a bit of what I like in NOS DACs (tonal density, material bass, upper-mid naturalness). The May KTE that’s on order will be a replacement for the Morpheus. I’ve read a lot of Wavedream reviews, some from people I trust from reviews of gear I know. I considered it, but those impressions did not quite convince me in relation to my particular tastes. I like the Spring 2 > Af > ZMF (various options) chain(s) so much that another Holo DAC and another 2A3 amp from a reputable maker were more attractive, especially given that I could not demo anything during the pandemic.
My low-confidence hunch is that the Wavedream would work better for me on a speaker system. But I just got a Linn Klimax DSM with their new Organik DAC driving powered ATC speakers, and this chain is completely slaughtering what I thought could be achieved in a living room. The Organik DAC is a weird beast, aggressive FPGA upsampling driving a discrete resistor array, probably closer in design to the Chord DACs than to anything else, but to my ears it weaves its way superbly between the NOS DACs I’ve heard and Chord. Anyway, that’s a digression. One day I’ll have a go at demoing a Wavedream, but for now I’m still firmly in Mr. Zhu’s camp for headphone system DACs.
