Quite a few Bricasti M21 DACs for sale cheap

I would say the Delta Sigma DACs in the M1 Series II and M21 sound identical to me. 

The M21 has a ladder DAC, which sounds marginally different than the Delta Sigma, so it’s an additional option for the listener. 

The M1 has many more filter options, if that’s important. 

I recently added a Bricasti M21 to my system. The M21’s ladder DAC is an interesting option to have.

I have to say, comparing the M21 to my M1 Series II shows how close the two Delta Sigma DACs are in every aspect. The M1 Series II is for sale, but I could easily decide to keep it and sell the M21. They’re that close.

Bricasti can upgrade their DACs to current specs. Current spec would include new display (red dot display is the older version), and current MDX (relatively inexpensive). Having both i2S and LAN inputs is not standard spec (at least it’s not shown on the Bricasti Design website), but I believe they can install both inputs if asked. It’s a custom job that requires machining the rear plate. @sksos may know more about this.

If one is able to buy an older Bricasti DAC at a good price, then it might be cost effective to have Bricasti upgrade it versus buying new.

Reach out first to Brian Zolner for upgrade options and pricing. Have the serial number ready from the DAC under consideration.

A quick search on HiFiShark returns four listings for M21 DACs. Two listings are from the same seller. There are two others listed. A total of three. None are current models (the displays are red dot displays), which explains the pricing. Internally, other than the possibility of an older MDX version, there’d be no difference from a new M21 (but reach out to Bricasti Service with the serial numbers, and Joe can verify configuration and update history).
