I am selling a Chord DAVE with Sean Jacobs ARC6 DC4 power supply and Sean Jacobs capacitor board already installed. I prefer to sell this as a package deal. If you want to make an offer on the power supply only, I will listen but it will need to be a serious offer.

Both DAVE and ARC6 are black. Also included is the Chord stand, in black with nickel feet, specifically made for DAVE. Combined retail on everything is $29,295 ($14,000 for DAVE, $12,600 for ARC6, $500 for capacitor board, and $2195 for stand). I am selling the entire package for $13,750, less than the cost of a new DAVE. 

Note that the price of a Sean Jacobs DC4 ARC6 has increased substantially this year. The base price is $9200. Add $2400 for the three ARC6 rails for the DAVE. Then add another $1000 for the Mundorf silver/gold wire upgrade. See

The DAVE/ARC6 combination is the Mt. Everest of DAVE sound quality. On the used market, you might find two or three listings worldwide for an ARC6 made for DAVE in a given year. Sean Jacobs never discounts these and they usually take several months to build.

Many of you reading this already own a DAVE and are looking to improve it. If so, you might consider what I did several years ago when I bought a Sean Jacobs DC3 power supply. I already owned a DAVE but the owner of the DC3 sold it to me as a package deal with his DAVE. I ended up selling my old DAVE. There were several advantages: 1) It's a turnkey solution -- I did not need to remove the power supply on the new DAVE since the DC3 was already installed and ready to play right out of the box; 2) I sold my old DAVE for a price that, when subtracted from what I spent for the DC3/DAVE package deal, came to an amount that made the new power supply much cheaper than any other option I could have found; and 3) I eliminated the problem of waiting for either a new Sean Jacobs build or waiting (and waiting) for the product to appear on the used market.

The DC3 took a great DAC to greater heights, but the move from the DC3 to the ARC6 DC4 was much more profound, specifically in the areas of 1) physicality, density, and dimensionality; 2) bass; 3) dynamics; 4) resolution; and 5) space. The ARC6 is absolutely the best upgrade you can make to DAVE.

The capacitor board is only available to DC4 owners and adds a certain lushness and beauty to the super-transparent ARC6/DAVE sound without softening transients or loosening time domain performance. See my mini-review here:

Finally, I will include DAVE’s original power supply just in case you would ever need to re-install the original power supply (perhaps for resale?).

Condition: I am conservatively rating both DAVE (with stand) and ARC6 as 8 due to age. I was unable to find any scratches or blemishes on either. Everything has worked flawlessly since day 1. The umbilical is hardwired into DAVE. You simply attach the umbilical to the ARC6, plug in the ARC6 (no on/off switch for greater fidelity), and you are up and running. The umbilical is about 25 inches long, so you will want to make sure the two units are in close proximity.

Purchase History: The ARC6 was previously owned but basically just long enough to burn it in. If I had to guess, I would say it was built in the latter part of 2021; I bought it in the summer of 2022. I purchased the DAVE from a previous owner in 2021. If I had to guess, I would say it was built between 2017 and 2019.

Shipping and Payment: Sales restricted to continental United States. I would consider shipping to Canada if the buyer takes full responsibility for shipping. Buyer to pay shipping/insurance. The DAVE and ARC6 will ship separately and will be double boxed for safe transport. For PayPal payments, please factor in an additional 3% for fees unless going through Friends & Family.

No returns: This will be a final sale, with no returns accepted.

Questions: I'll do my best to answer any questions in a timely manner.

Dimensions/Weight of the gear itself: ARC6 is 17.75 wide x 12 deep x 6 high (44 lbs). DAVE is 13 wide x 6.5 deep x 3.25 high (11 lbs). The umbilical is 25 inches long.

Questions for the seller
Does this work (well) with the chord scaler and/or did you decide it was not a worthwhile addition for some reason?
Hi John, thanks for the question. I used to own the Chord M Scaler and considered it a great addition to the system. I powered it with a Farad power supply, a good upgrade over the stock supply. I sold the M Scaler when I started upsampling files offline with PGGB. I believe that the Sean Jacobs power supply I am now selling could be modified to power an M Scaler. For the M Scaler, that might be overkill. Not so for the DAVE, which benefits tremendously from the best power you can feed it.
Do you have the Mundorf silver/gold wire upgrade you mention? I ptrsume the $13,750 mentioned in the ad is the correct price rather then the $14,250.00 at the top of the page?
Yes, the power supply includes the Mundorf silver/gold wiring upgrade. Thanks for pointing out the discrepancy in the two prices -- my mistake. My asking price is $14,250. I am happy to receive all reasonable offers.
