nihaoluc Posted January 13, 2020 Posted January 13, 2020 Hi Hyper! I'm currently working on a dac-amp box with the Purifi dual mono kit Luc
nihaoluc Posted January 13, 2020 Posted January 13, 2020 I originally planned to use a dual mono NC500, but it looks like the Purifi goes one step further in audio quality and ease of integration
hyper1624705763 Posted January 13, 2020 Author Posted January 13, 2020 I heard Gentaudio is planning a full kit for it... I am gonna wait a while to see what he is offering. The evaluation kit is less than 1K and if u add the SMPS we are looking at 1.5k for a top end 2 ch 400w stereo amp. I initially wanted to get from Nord but decided to wait after hearing Gent is offering a full DIY kit.
hyper1624705763 Posted January 13, 2020 Author Posted January 13, 2020 Hi Hyper! I'm currently working on a dac-amp box with the Purifi dual mono kit Luc Wah so adventurous.... which DAC module are u using and what power supply?

The evaluation kit is less than 1K and if u add the SMPS we are looking at 1.5k for a top end 2 ch 400w stereo amp. i bought the purifi amp kit (dual mono + buffer) and an hypex smps3ka400 for less than 1k €
nihaoluc Posted January 13, 2020 Posted January 13, 2020 Wah so adventurous.... which DAC module are u using and what power supply? planning for the Soekris R2R dam1941 dac power supply, i've already purchased the hypex smps3ka400, but i may change my plan. thinking. maybe the cresnet, using 2 of them
jaffrie Posted January 14, 2020 Posted January 14, 2020 Everyone likes different flavors. I would recommend that you go with linear ps. Have played with hypex for a while including 2 versions of the smps & at the end of the day the linear ps wins, ps caps used where Mundorf Mlytic & Shindengen rectifiers.
hyper1624705763 Posted January 14, 2020 Author Posted January 14, 2020 What’s the diff between SMPS3KA and SMPS1200A400? Hypex recommend to pair the NC400 and 500 with the latter one. As for DAC, I just bought iFi Zen for MQA decoding and would leave the amp separate. I use my old IPad 2 as source streaming from Tidal. Best thing that happen since Spotify. Tears for Fears in Master quality is just sedap.... Vivaldi, Bach. I stream in my car with Tidal and the sound is also very good.

Hi Jaffrie, Thanks for your info! What model of linear ps did you use?

jaffrie Posted January 15, 2020 Posted January 15, 2020 Hi Nihaoluc, Just simple EI trafos, I like to build my amps in mono mono hence seperate PS. If you can, look for split bobbin type.
hyper1624705763 Posted January 16, 2020 Author Posted January 16, 2020 just the power. Nord uses one smps1200 per channel in some of their amps. The 3k can replace two 1200 I am leaning towards individual SMPS to power the modules. Likely be using smps1200 on each modules base on mono block footprint. I gonna stack them to reduce space
nihaoluc Posted January 21, 2020 Posted January 21, 2020 Micro-Audio are currently finishing the development of an SMPS specific for the Purifi amp module. Soon expected. Their ps are recognized especially for component quality and low heating. And price is good too. Usually evaluated better than Hypex'. https://www.micro-audio.com/index.php?route=product/category&path=59 Waiting for the release...

The 600W SMPS looks to be a good form factor to squeeze for dual mono in a small chassis... unless u put in those additional input buffers. When are u going to start ops... can I join u? :)

Perfect for Hypex NC500 amp in a dual mono solution ;-) When are u going to start ops... can I join u? :) Very soon ;D Waiting for the DAC that will arrive quickly and I start mounting. What do you mean with "can I join u?" ?

I am still thinking whether to get Purifi or just get the NC400 diy kit. The latter needs only 30 min to assemble and hola you got a pair of top class D amp for less than 2k

The latter needs only 30 min to assemble and hola you got a pair of top class D amp for less than 2k the dual mono Purifi kit plus power supply will stay within 1.5k. the tests i've read so far tend to say the Purifi goes one step further in sound quality
