Didn't somebody use some larger VitaQ's for ahome build. I have one in a ciogar base box with polenty of room for exotic caps. Any recommendations?

Thanks

I did with 0.68uF VitQs bypassed by 0.047 MKPs. It sounds warmer more defined to my ears than the 1uF Vishay MKPs. Although the Bantam sounds great I would not spend more on output caps because the DAC is limited by its chip.

That's what I thought

I'm hoping to solve the problems with mine tonight. I ended up at work today

We had a drive failure, so now I'm watching the array rebuild.

Well, I'll disagree a little bit with jERiCHOh. I think my BantamDAC with the Vishay-Roedersteins sounds better than my 0.66uf (three 0.22uf in parallel) Alien DAC. The VitQ's are just a trifle light on bass, while the Roedersteins are just d*mn fast, meaning highly detailed compared to the VitQ's. Yes, the VitQ's sound more refined in the mids and have outstanding musicality, but paired with my MiniMAX, the Roederstein BantamDAC sounds like a better combination.

I totally agree with you tomb ! But bypassing them with MKPs seemed to give the output more fastness. Well... to my ears. I must say I'm more into trying to correct the sound from my "downloaded" music than full bass response.

Jericho, where did you find the VitaQ's at?

 

[jERiCOh]

Ebay... The seller I bought it from has no more big ones but I found those ones for you.

beezar.com, which tomb runs, sells them in two values, at a couple few dollars each -- a generous service to us DIYers. You can configure them in parrallel to get higher values.

sorry guys i'm a total SMD noob other than ipod mods. the bantam kit arrived today. i'm assuming the resistors are non polar there are a couple with numbers on that would have some way of orienting them if that was the case, but most have no distinguishing marks whatsoever and look the same one way as the other

Only the IC's, the two electrolytes, LED, and usb connector are polar.

Exactly right.

BTW, in the layout pic below - "+" is at left for the LED.

TomB, is the long lead +? I swear that's how I put mine in a few days ago, but it was definitely backwards.

EDIT: Is leaving the DAC plugged in, but not to a source, beneficial for burning-in? I don't have my amps home on break with me, but I've still left my BantamDAC plugged in anyways..

Long lead is "+", positive. Quote:

No, but it won't hurt it. I typically have mine connected to a USB port on the computer all the time. However, no current flows through the output caps unless it's connected to something and playing music.

cool thats what I thought

thanks lol @ the usb connector hehe, but i've heard they sound better when you reverse the polarity

 

[qusp]

again sorry for the noob question. when reading the schematic am I to assume that + will always be on the left when oriented the same way as the lettering indicates ie. with the output caps and everything that IS polar. so when oriented on the same way as the text for C7 or whatever the positive lead will be on the left as a rule??

ok i'm going to sleep its 4am and i've got a big bantam day tomorrow

will check back in the morning befoer I have my jug'o'coffee and get going on it.

also is there any booze that I can substitute for pure alcohol for cleaning the PCB after i'm finished?? ie vodka

one for me one for the bantam
