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.

@laoman : that if I recall was the $349 Topping Class D amp. A new product. ASR considers the $3K Benchmark ABH2 amp to be the best in their survey. They rate the Benchmark DAC to be in their top class. 

@laoman : ASR has also given thumbs up to four-figure DACs. The measurements made using the Audio Precision APx555 are comprehensive. Regarding problems with cheap gear there are plenty of posts here about expensive gear needing repair.

This was a common way for sales men at audio stores to sell speakers! They made sure that speaker A was just a wee bit louder than speaker B. The customer always preferred A! 

Lot of hate here for Amir and ASR! Measurements do matter! More so than "golden ears" listening because human hearing is easily fooled! Trying to have a discussion here with subjectivists is like Galileo confronting the Inquisition! 

@mastering92 : so you imply that Amir is being bribed by unscrupulous audio manufacturers? And that's why Benchmark is highly rated? I'd like to have Amir respond to this!

As an example in an A/B listening test of two preamps, amps, CD players ... the component that has an output level 0.2db higher will always sound "better" - more exciting, more lively, more engaging! All due to a simple level difference! Yet most audiophiles are ignorant of this psychoacoustic fact! 

@mastering92 : why not level the same charge at the scribes that write for Stereophile, TAS, HiFi+ ...? All those glossy ad pages ...

@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.
