sorry for delay, i was really busy this fews day, thks for helping me quoting on that, i had ordered one D1, wish it come to my house soon. and i read all u guys wrote that D1 modded might on par with XIN, if it is real.....

i will be superly

You're still living in the analog world...

I find it really hard to tell the difference between the 2 DACs, as it is not possible to run the Move DAC thru the D1 whereas one can route the D1 DAC output thru the Move.

The differences between them, therefore, are more between amps sections than DAC outputs.

I don't think anyone will be disappointed in the DAC in either amp.

Ron, do you like the D1's amp more than the Reference?
How long is battery life with the new configuration? And which of the two amps can reach the highest volume?

 

[jaspert]

Hi Ron,
Where can you source AD 8397? I have an incoming D1 and a noob at this op amp rolling business.

cheers,
jasper

 

[dissembled]

Seems like the D1 is enticing lotsa folks to try their hand at this whole op amp rolling business.
Including me. :very evil:

 

[visia]

Is there any source for OPA2111? It seems to be out of stock pretty much everywhere.

 

[nv88]

Could some nice soul do a step by step with pictures of switching the OP amps? I'm sure a lot of us noobs would be greatful. I would also like the source and parts numbers to make sure I'm buying the right things.

 

[cursory]

And who here even knows what op amps are?

(I don't either.)

 

[ehlarson]

I've been looking for something like the move, but more versatile for quite a while. I've been considering the Apogee Mini-dac, but wasn't sure whether or not I wanted to spend that kind of cheese, and whether or not to get the firewire or USB version.

Now look what you've done. A DAC/AMP _portable_ almost as versatile for 1/4 the cost WITH easy mod capabilities and what looks like very nice build quality.

Looks like a serious winner. I ordered one Sunday. Hope it gets her SOON.

Not only in bass, mids, etc, but especially in the 3-dimensional rendering of the soundstage and imaging. No soldering is necessary unless you wish to change to higher quality capacitors. It only requires that you unscrew 8 hex screws and one phillips screw, then the amp just slides out of the case. The opamps and buffers are right in front of your eyes on the top side of the circuit board. Rolling opamps ranks about like changing light bulbs in degree of difficulty!

So is soldering necessary or not to use the AD8397 for the buffers?

I 2nd that

The AD8397 are surface mount devices (smd) in a soic form of chip. They have to be either soldered directly to a printed circuit board (pcb) or to an adapter that will go into a socket on the pcb. The socket takes chips that are in a larger package called a dual in-line package (DIP), but the 8397 only comes in the soic form so you have to solder it to the adapter but they are small and experience in soldering is needed. Brown Dog makes adapters for this purpose.

 

[kramer5150]

Does anyone have sonic impressions with Grados? I have (generally) found HD650-synnergetic amps to sound terrible with the RS1.

What is the amp gain? Is it low enough for low impedance IEMs?

thanks in advance

 

[antonyfirst]

Yeah. How does it sound with the ER4P/S?
