so there are still people using these, huh? i had thought that with the advent of the hi-def format cards, these would have gone by the wayside... good to hear these cards are still being used!
in fact, i still have mine lying around if anyone is interested... it would be nice to sell it to someone who will use it rather than have it sit in its box gathering dust.
just send me a pm...
Hi Anthony Just for your information, my audio playback system is 2.1, utilizing the X-M with 2 separate opamps, one for bass (subwoofer) AD8066 and the other being the (front channels) OPA637's. Hope this helpful.
Rock music is my vice. Rock bands consist of bass guitar players and percussionists with kick drums. The impact of bass in rock music sets the timing or pace for the music. Bass also gives the music depth and dimensionality.
The Analog Devices AD8066/65 opamp really do "KICK and SHAKE"
So what do the ADs bring us more than the LM4562's for bass.
The AD's are more weighty, authoritative, controlled with more grip being tighter, faster with more attack or rythmic pace as well more definitive and articulate. Extension , dynamics or slam factor are equivalent to the LM'S but the bass notes are by far more clearly heard on the ADs. The LM is muddy and overly exaggerated. Bass notes or tones are not nearly as distinctive.
My system includes a powerful subwoofer with extension down to 21 hz. My music listening tastes are generally new hard rock including artists like Seether, Theory of a Deadman etc. As well I listen to Pop,Dance and R&B being J.Timberlake, Rihanna and others.
About the Burr Brown OPA637AU vs LM4562s
I find that the OPA637s excel in clarity, smoothness, being more refined in the vocal and upper frequency range of the scale. As well, the presentation is much more musical bringing warmer fluid harmonic textures not to mention better separation of the instruments. Bass seems to be more limited between the 30-75 hz(after numerous hours of usage) and not as controlled, defined or extended. Upper range details are not as detailed as the LMs But the 637s is far more smooth and silkier.In comparison the LM4562s are much harsher, thinner and as said before more metallic in the upper range. Bass is much more extended, more grip and definitive than the 637s. Overall the LMs presentation is somewhat sterile but more dynamic or punchy. The OPA637s are somewhat laidback.
I could easily live with the OPA637s but I do miss the bass extension, definition and dynamics, rythmic pace, attack or slam factor. Between these opamps I would pick the Burr Brown OPA637s. So that's where the AD8065/66s come into play. Now I have the best of both worlds.
There will always be trade offs between opamps. No opamp is perfect. Its just finding the one that can cover the most bases in your sonic requirements for your own musical tastes.
