No, the odac is directly hooked into the o2 amp. If you want to get nifty, there are ways around this, or you can purchase a different configuration from my own store.

I would be interested in reading a detailed description of the ways to "get nifty" with it and get a line-out port / functionality -- a write-up on your website and a supplemental parts package for sale there would be a neat way to one-up the current offering. People who are considering stretching their wallets to get this might not all think the rear-mounted power port is worth the extra $45 in base markup ($35 in MSRP, $10 in shipping) vs the normal offering on your site -- expanding the versatility of the product design, however, could be an effective clincher.<br /><br />Also, could you provide a brief description of the power options on the combined Amp+DAC since there are no batteries involved? Seems like the supplied PSU is 15VAC (5V @ 3A?). Can the combo run purely off the USB bus with a Y-connector? Or can it be powered partly by the USB port and then partly by DC with a separate USB-to-DC-Barrel cable? Put simply, is there any way that 2-3 adjacent laptop USB ports could have this thing running without an outlet nearby?

You can purchase this<br /><br />http://www.jdslabs.com/item.php?fetchitem=49<br /><br />and I can include a 3.5mm jack, you would just have to solder it on. If more than one person is interested, they can email me and I can get a kit going for extra money.<br /><br />The increased price from my website is only $35, you get charged roughly the same on my website for shipping. The increased cost comes with the custom front and rear panel, as well as the cost/labor for installing the rear power jack. It's not that much of a mark up.<br /><br />The power is supplied via a 12VAC .2A for US plugs. 220v power supplies are 15VAC at 500 mA.<br /><br />The combo needs to run off of AC and be connected to USB. If you decide to add the output in the rear of the amp for the ODAC, than you don't need the A/C power supply.<br /><br />This amp can not run off of DC power.\<br /><br />Again if anyone is interested in this kit, please email me at mayflowerelectronics@gmail.com<br /><br />Kit will be an additional $10.

Sorry for the mix-up on the amp PSU -- I saw that photo with a number divisible by 5 and the letters 'V' & 'A' (thinking 'volt-amp') and my brain cramped. Wishful thinking. Re: the markup, I wasn't questioning the value of the effort you put into it, but rather the relative value that *some* prospective buyers would put on the feature vs your regular-priced offering of the reference design. <br /><br />Re: the ODAC line-out mod -- I'm assuming you mean that we're buying that special plate from you (not JDS) and that you would then apply your rear power port mod to that... along with the soldering of the jack? Considering the simplicity of the mod (I was expecting something much more complicated than that), I would think the $10 option should include the soldering -- you already said your guy is doing some soldering during assembly. On another brain cramp, I don't know what I was talking about with putting the supplemental kit on your site for separate purchase -- whether you apply the mod or the buyer does it, it should just be added as an option here on the drop to make things easier. <br /><br />In the future, I think you should consider tweaking it and instead of the rear power port, offer the RCA inputs and the line-out mod for the same $229 lowest-drop point. [There are so many people on this site that already have a portable battery-powered amp of some kind (e.g. Fiio products) that a USB-only driven ODAC option brings real cost-effective versatility to the combo product.] I have a lot of respect for NwAVGuy's work and his entire contribution to high-end audio, and seems like you have a great operation going, so really hope this all works out.

It's not possible to do the line out/rca for $229. There is not enough room for profit.<br /><br />As is you can't have power in the back and RCA's. The rca's pick up the hum of the 60hz from the power supply in the back (long and complicated explanation). <br /><br />I have not gotten much interest in the mod so far, only a few people. So for now I don't think I'm going to offer the option. You can use an RCA to 3.5mm cable if you already have another DAC, there's no need to add cost to the amp that you can solve with a $3 cable. If this drop doesn't happen then we will consider a different versions but there's still 5 days left.
