Built-in vs. Standalone DACs


The general consensus here seems to be that standalone DACs are generally better than those built into an integrated amplifier. Many also agree that standalone DACs provide more flexibility, i.e., you can swap DACs without changing the amp.

For the sake of discussion, let’s set aside the flexibility argument and only focus on sound fidelity for now. The primary advantage of a standalone DAC is that it provides better isolation (reduction in electrical noise) since it’s not sharing its architecture with other shared components like power supplies and chassis, etc. I’m also assuming that service and repair is a bit easier as well. What other technical advantages can you guys think of?

Another salient point that I’ve come across is that many manufacturers treat a built-in DAC as an afterthought, and so while the DACs might not be bad per se they are never the star of the show. As a result, the manufacturers don’t go the extra mile in a way that a company producing standalone DACs might. I think you can put Krell, Hegel, McIntosh in this bucket. If you disagree, feel free to correct me.

But on the other hand, we see some high-end manufacturers providing built-in DAC modules and charging quite a bit for it. Examples include Accuphase, Gryphon, Aavik, Soluution, Audio Research, etc. In many cases, the addition of a DAC module can set you back an additional $5-7k. Do you guys think the high cost is basically a ’convenience’ surcharge, or can these high-end built-in DACs compete with DACs that cost about the same, e.g. standalone DACs in the $5-10K range.

So let’s say someone is ordering a Gryphon Diablo 300 and have to decide between adding their DAC module, or buying a separate DAC. Ignoring the flexibility argument for a minute, which route provides better SQ?

Honestly I wonder about the separates argument in the highest price tiers.  If I bought a streamer/DAC combo, or integrated amp/DAC, in the $20K range, I would expect the DAC to be damn good, and not an afterthought.  Separates might make more sense in the $5K range, where a standalone DAC is likely to significantly best one included with another component 

And then there is the advantage of less boxes and cables.  This is a reprise of the integrated amp vs separate pre and power amp issue.  When the high end companies such as ARC started making really good integrated amps that sounded basically indistinguishable from separates by the same manufacturer, the theoretical arguments for separates were more justifiable at a lower price point
