@steakster : congratulations! You are some sleuth! Yes, I am "roberjerman" and I have 4319 posts using that moniker. I suggest you read some of them! I changed my alias here on Agon because I couldn’t log-on when I got a new phone. I did buy a pair of speakers at the Greenwich Village, NYC Crazy Eddy’s in 1976. A pair of Acoustiphase two-ways large boxes - an Advent copy - for $200. I used them for a few months with a Marantz 2270 receiver. Sold them in the spring of ’77 and bought a store-demo pair of Infinity Monitors 1A with Walsh tweeters! By that time I had an AGI 511 preamp, GAS Son of Ampzilla, Mitsubishi DA-F10 tuner and an Empire 698 TT with a Dynavector 20B homc cartridge. How’s that for a late - 70’s high-end system! Speaker wire was Polk Cobra Cable and ICs were Verion Triaxials made by Mitch Cotter.
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.

A costlier DAC should, at least in theory, produce more accurate output. Specs like ultra-low THD are not very important when considering which DAC to buy. Like I said before, if you can’t hear it, it doesn’t matter. Tons of negative feedback in the circuit and other shortcomings...and many who have not heard a lot of audio gear before are quick to praise it...simply because it produces sound/ouput!! Ranking by cost alone may not provide the results you want. It’s all about the design topology, quality and longevity ratings of internal parts, protocols, USB controllor specs, and of course the designers intent. Do you want a very detailed DAC? then go hunting for "accurate or resolving DACs" online. A lot of pro audio gear (such as steinburg interfaces, for example are more suited for recordeding and will not reach the same level of performance as a standalone DAC. Once again, cost savings. At any rate, software settings on programs such as jriver can alter the sound quality of a DAC in many different ways. If you’ve got a resolving DAC that sounds cold for example, you can easily fixate its tonal quality to be a bit warmer and easier on the ears. The details in the music will still be there...just less obvious or upfront. I’ve read quite a few of @jasonbourne52 posts, and much of what he says is practical and makes sense.
Right, these folks don’t match for LUFS!! Look this one up... Other problems include excessive dithering, not converting a CD quality file to 32 bit by 96 KHz or higher, dynamic range compression, Equalization mistakes, etc. And you’re absolutely right about that. Having to turn down the volume because of problems with loudless won’t allow you to experience full extent of the music. Which tracks? I’d love to fix them. |
