Sony TA-ZH1ES headphone amp! Got it for $900 used but basically new from a guys summer home.
Have an unnamed $3500 new headphone amp that hasn’t impressed me much after listening to the Sony with my Z1R’s. Can’t say enough good things about theTA-ZH1ES.
As far as other gear goes....
DAC: Cambridge Audio DACMagic 200. $500 and love it. Its just a great DAC and scratches the MQA itch for cheap. Powers my in ceiling and outdoor speakers along with my Stellar PS amp. However a Bluesound Node is still a better bargain since the streamer function is there.
Speakers: JBL 4309’s got them new for $1200 on sale and OMG love those sealers immensely. Paid double for speakers and haven’t enjoyed them half as much.
Amps: Schiit Aegirs in mono! $1600, mono amps and an incredible sound. Again, super enjoyable! But two new Azur 851w’s for 3k is a close second.
Integrateds: Technics SU-G700MK2... Not really cheap ($2,900), but really is a product that just wowed me start to finish. Sound, looks, tech (LAPC), etc. I remember having 4 integrateds in my house and the Technics outshined them all (Yamaha, Rotel, CA).
Headphones: Austrian Audio HiX55’s for wired headphones ($350) incredibly detailed and neutral sound.
BT headphones: Technics A800 for $275 new are a steal IMO.
Hifi at price point really does something. I honestly love hunting down pieces for certain price points and feel it adds to the experience.
