Pros & Cons of Buying an Integrated with Built-in DAC?

@bcgator 

I both agree and disagree. USB receiver chips and clocks have come a long way. If you are using modern D/S chips these are imporant factors to the overall performance. This is the only kind of DAC you will find in fully integrated units.

Personally I use a R2R filteless DAC which is 6yrs old & prefer it to far newer and costlier units. However this technology has obvious testable tradeoffs for the things that it does right which are masked to some systems/ears regardless. Digital's more recent advancements are less important here simply as these designs work differently. I figured it would over complicate matters bringing this tech into the discussion as it involves niche markets or vintage purchases(and the convertex boxes which come with.)

It is much like the debates over amplifiers. Class D makes great advances every year whereas Class A sees more subtle refinements. Most everything is up for debate other than Class D amps outdate quicker simply due to the markets focus and more rapid advancements. 'Marketing' is the simple but perhaps incomplete answer.

Ah yes, great point about the advances in USB chips and the adoption of asynchronous implementations.  That has been a welcomed advancement.  

I also think that there are many older DACs (5-7 years old, possibly older) that could serve well in todays system. For computer audio most would require a USB/SPDIF converter, however this also is no problem as many good ones are available on the used market. Buying a used older DAC often provides for a much more robust power supply and analog stage for the money spent.

I have ended up with a Wells Majestic integrated. I don't miss tubes at all with this amp-- it sounds incredibly musical to me-- very engaging in a non-fatiguing way yet more dynamic and dimensional than my tubed Jolida. Yes; in the end, I had to spend considerably more than I'd originally budgeted, but my goal was to buy my "last integrated". It's upgrade-able and built in USA-- only a couple hour's drive away from me. All concerns about DACs have evaporated since the Majestic has been in my system. Jeff Wells even burned it in before shipping it. He's a real pleasure to deal with. I'm really happy. Thanks to everyone that contributed to this discussion. 

Congrats! I am not familiar with this integrated. Will look it up.
