[Henrik Nordberg]

I have been following this forum for a while and finally decided to build a DAC and an amp. Since others (especially amb and Mister X) have contributed so much, I thought the least I could do was to post the BOMs for the units I will build (σ11 + γ1 + M³). Also, happy birthday amb! (Noticed it in your profile, since it is my birthday too.

)

If anyone has comments on the BOMs, let me know. I will try to fix any mistakes. I am ordering these tonight from Digi-Key and Mouser.

The following are for Digi-Key. Copy and paste into their BOM wizard.

All for M³ except last two, which are for σ11.

I am sure I missed something! So I will update this post as mistakes are discovered. There is no warranty for speling or that the lists are complet.

Since this is my first post.... Electronics used to be a hobby of mine a looong time ago. I am so excited to have found this forum with such a friendly and helpful community, and to get started building audio components. I plan to use the units at work where I spend my days by a computer (programmer).

Cheers,
- Henrik

Hi mate, any chance you can update us with the total cost once you're done? Thanks.

 

[ShinyFalcon]

According to my messy BOM...

M³ Mouser = $41.89
Sigma Mouser = $24.89
amb M³ = $77.35
amb sigma = $27.19
Digikey = $36.56
Total = $207.88 (not including shipping and tax)

This is not including cases and little bits of pieces (RCA jacks, knobs, fancy stuff) that I don't need/have not thought about yet. Those kind of stuff can easily bump the price maybe $50 or $100 more. I kind of favor function over form, but for my next project I want it to look very nice, thanks to zkool448.

 

[pdupiano]

hmm yeah just as I thought... a balanced M3 might be more expensive than I thought... .. my wallet's gonna murder me in my sleep

On the plus side, its a lot cheaper then a balanced B22 setup

 

[pdupiano]

... my wallet's gonna jump you in your sleep Mr. Bojamijams... you better get ready in your pajamijams. Yea I'll stay away from the B22 for now

 

[Punnisher]

Thanks for the lists. I'm about to build a M3. Wallwart for now, but maybe σ11 later if I'm up for it. This should make things a bit easier.

Edit: Please do not copy/paste my BOM, it can lead to great mistakes! Use for reference only.

This is my previous Mouser order for the y1 DAC, full build:

and similar for my M³; there are some additional resistors/caps for different gains and playing around with bass settings, and I think there's parts for a TREAD PSU too...:

Hmm, it seems like a balanced M3 is out of the question for me, at least for a long while. Too bad. I'll make a balanced SSMH to tide me over until then. Maybe even a balanced Bijou. It seems to be cheaper.

 

[ShinyFalcon]

And with balanced amps there's a need for a different pot as well... the balanced pots I've seen are pretty expensive!

Have you tried anything balanced before? There's someone here who turned two Mini³s into a balanced amp. It seems like a great way to enter balanced, $100 in parts (~$50 per Mini³) + balanced pot + case.

 

[Ishcabible]

SSMHs are approximately the same cost for parts, so I'll go with that instead. I've always wondered about tubes too, so it makes the most sense to do it.

Fwir, the balanced mini3 is kind of pointless when a single ended M3 supposedly sounds better for around the same price, maybe a bit more.

BTW, it was Rockhopper Audio that made them and I think still makes them if anyone reading this is interested.
