Looks like the impedance of those headphones is 64ohms. It will handle those no problem.

@godbluff Out of the hundreds of DG releases, I am trying to find which remasters and releases specifically had the best sound quality. Are there any databases or forums where people post reviews of specific remasters of the same recordings?

@EDN80 My initial research shows that The Originals series you recommended for the Bruckner was not as good of a remastering as the earlier CD releases in the 1980s.  Can you shed more light on this?

There are so many analog to digital transfers of Karajan's recordings, can anyone direct me to specific albums, collections, or even record labels that did the best job of remastering and transferring to CD format?  Any help is appreciated.  

Glad I read this before dropping $39!!!

I would go beyond saying they are unreasonable for the price/sound quality ratio.  I would say they are garbage at any price.  

So most of the advantages come with ripping older CDs that may not be in the best condition right?  If I were ripping a brand new CD, there would be no possibilities of error?

Hello,        After doing some research on this website, it seems like many people recommend using CD ripping programs such as EAC.  Until now, I have been using itunes to rip my CDs to AIFF format.  Does itunes not provide bit-perfect ripping? And will it make a difference to switch to a...

An excerpt from a Stereophile review:  "The sonic differences between the original and v1.2 DragonFlys were almost as obvious as those between the Sennheiser Momentum and B&W P3 on-ear headphones. Where the original DragonFly excelled in clarity and detail, v1.2 added a richer, more colorful...

From the website: "Among the improvements, the circuitry between the DAC chip and the analog output stage has been refined to create a more direct signal path, leading to even greater transparency and immediacy. Also, the DAC’s power supply has been fortified, which gives the sound more “grip,”...

Sennheiser makes the PXC450.  Never tried it but a lot of people seem to like it. I feel that around-ear headphones are more comfortable than IEMs for extended periods of time.   

Is there a difference between the newer Q701 and the K701? (Besides the new branding)

This is starting to sway from the original topic, but higher resolution audio does more than increase the frequency range.  When you change from mp3 to AIFF for instance, the soundstage will open up quite noticeably. 

I agree with saxelrod92.  Bandcamp has some artists, and the option to download FLAC, but for mainstream artists you're probably gonna have to buy the CD and rip it.  I also agree about the music player software.  If you are planning on playing hi-rez file formats and/or planning on buying a DAC...

Unfortunately, the main audience of the music you listen to does not care about sound quality, especially since most popular music can be illegally downloaded for free.  Classical music, jazz, and rock seem to find the biggest support for high quality files (try listening to orchestral music at...
