Analyzing DACs


As I am new to the hifi hobby, reading various product reviews and noting the details of the test environment have made me very confused.  I understand Stereophile is the hifi bible. In the publication’s DAC published tests the reviewers almost always tested the DAC connected directly to the amplifier. I think I understand why—nothing in the chain influencing the DAC sound. Is that the correct assumption? If that’s the case why incorporate a preamp if the DAC has a preamp section that is a common feature even on high end DACs? I’m in the market for a new DAC. I’m trying to avoid unnecessary components if possible. Any thoughts would be appreciated. Thanks.

If you don't have a preamp, it cannot degrade the sound.

Listen to a DAC direct to amp at low volume and then listen to the same DAC via a preamp like the Benchmark LA4. There are some expensive DACs that are similar to the LA4 level of volume, such as the Lumin X1 with Leedh volume control. All DACs I have owned in the moderate price range were not good direct to amp at low volume.

 

@verdantaudio Have you compared the Lumin X1 DAC in your shootout? I need to get another DAC and trying to find a reason not to get a second X1. Variety would be nice or maybe not, since I like the X1’s sound and features. The other DAC I have on my mind is the Musetec 005, which I have owned before and much cheaper and also like (but no streamer)

I am curious about other DACs in the higher priced bracket. Along with DACs that have USB as their best sounding input, like the Musetec 005. I will stream with fibre optical Sonore OpticalRendu (fibre-to-usb) if I do not get another X1.

I will go with a 2nd Benchmark LA4 preamp and currently the CODA #16 amp. Although, I may keep the CODA #16 in the office system and get a KRELL XD amp for the new DAC.

In my opinion, the DAC is the second most important component after the speakers - it is creating the signal you listen too.

Agree on this.

@verdantaudio That sounds interesting. If you are a dealer for that unit lest talk a bit more offline. I will send you a DM later.

@tee_dee Look at the tech in Mola Mola tamabqui (though old now, still unique). PS Audio, Playback Designs, and Chord with their FPGA approach, which I think is something that potentially can last for a very long time. This is new DAC technology. My next DAC will be an FPGA.

A 10 year-old DAC may not even have a USB input and if it did it is likely really bad, say unlike the USB on the modern Musetec 005 DAC.
