- I'm thinking of running the dac voltage out, the a and b dac parallel and in phase via a high pass filter to a single ended output without any transformer. That would just give me 1 v ouput, but I think it would give me enough level in my set up. Is this a good or bad idea?

- How good is the digital volume control compared to an analogue one? I'm thinking of skipping the preamp and running it directly to the amp. Is this a good or bad idea?

The Buffalo module:

1) it does not use internal input switch
2) it need an external custom module to change filter registers
3) it need an external custom module to remote volume and other functions
4) it is not integrated with USB module to play DSD and Hi-resolution tracks
5) it need external modules to change input
6) it have no shield to reduce interferences

I use digital volume control and no preampl. without problems.

I think the Buffalo supplys are bad designed . Oscillation problems etc.

yep, it's the best DAC I had in my system.

Good idea.
I've removed my preamp and have this DAC directly(LL1684) connected to my amp.
The ES9018 has a very good digital volume control: if the signal is attenuated than the noise floor is also lowered.

Hi!
Thanks for your answers.
- What are the main purpose of using transformers instead of direct out via low pass, other than the voltage gain?

- Is the software capable of shifting the phase of the b dac so they can be connected in parallel? The purpose of this would be to get a unbalaced connection directly from the dac.

Best regards Christian

After changing to SE out off 1684 ( 2 Volts) and using Jantzen 15 uf. ( Red ) I love the sound. Best sound ever by a great margin. Just wonder why I have some hum. I have soldered 4 and 2 together and 5 and 1.

No connection between Gnd in and out.

Hi

#1 Can you pm me shipping for #6 or #1-2-4-5, from what i'v seen shipping the chassie is expensive, to Country=Canada province=Quebec potal code= J8c 2Z7

#2 i've got 2 monoblock power amp ( Marantz SM-17SA ) used in BTL ( bridged ) here are the specs (see link), dosent say that much but do I need anything other than what is included in full assembly #6 to use this dac as a dac/preamp from what i figure this would help

- variable voltage gain only changing a single resistor (I/V)
- 3 voltage amplification setting with jumps

or do you suggest another output stage ?

thanks for the info you got a very intersting package

Normal SE connection is like this.

Try connecting PCB/DAC ground to RCA out ground.
