DAC diminishing returns

@firstgrowth Well, I didn't want to read that but I can believe it. The 502 seems very impressive and I am probably right where you were at. I am currently running a Denafrips Venus II and am waiting on a new HoloAudio May KTE, hoping this will be my end game DAC as the 502's price point is double my budget. Fingers crossed. 

@firstgrowth , the 502 looks like a cool toy. I mean that in a good sense. Do you personally set and forget it or change the settings to match the music?

Until earlier this week I would have agreed that the law of diminishing returns does apply to DACs (as it does to other hifi equipment in my experience). I started my streaming life with a Logitech squeezebox with built in DAC, moved on to their Transporter, then to a Lumin D1 and from there to separate DACs. First a Chord 2Qute, then a TT2, then added an M-Scaler (upsampler). Last week, I managed to find a good deal on a used Chord Dave. I was expecting similar incremental improvement as with all my previous upgrades, like slightly better placement, separation, somewhat tighter bass perhaps, more natural voices, even less sibilance, better reproduction of ambient sounds/noises on the recording. But I have been absolutely blown away by this upgrade. While it is bringing improvements on all these fronts, it is in doing so in spades. It is as if I am listening to a whole new system, sometimes suggesting multi channel presentation even though it is stereo. It has by far exceeded my expectations. Now, in fairness, the Dave, even at the second hand price I paid, was about double what I paid for the previous TT2. I leave it to you to consider what you would find a reasonable expected return for that extra money, but I have been surprised and blown away by the improvement it has brought to my system. I’m afraid the only way to establish the improvement a DAC can bring is to try it out. Hope you will find an upgrade that brings as much listening pleasure as my most recent one!

Shouldn't preamp, analog volume control be considered part of price/performance ratio. Many dacs don't have any means of volume control, others strip bits. In order  extracting maximum potential from these dacs requires some form of volume control, the quality of that volume control has major bearing on sound quality of that dac. Dacs with quality analog volume control built in may be far greater value than many assume at first glance.

@sns If you are building a minimalist system, built in volume control on a DAC\Streamer could be a huge cost savings. Then you have something like the Weiss 502 DAC mentioned above. Initially the price seems quite high, and I would say purely for the bare DAC electronics it is. However, when you include all the software features (if you use them), it seems reasonable for what is likely a relatively low volume product.
