Op-Amps: LME49710 vs. Muses8920/LME49720/OPA2134 ->more „contur“
got finally today my Dual-Dip 8 converter (1,45€ Ebay) LINK->
that i can use my bought, nice „LME49710“-s (they are single)->
a lot of „contur“; more than the Muses8920; but no so „lively“ as an OPA2134 for example (or the Muses.)
i guess its absolutely because of the lower distortion; also a little bit „cold“ (all only my impressions; some would feel maybe different about it)..
but its also a „high-class“-duo/OP-AMP ; see this table again->
(and curiously absolutely exact my impressions about them; in only hearing them „out“ here..)
Conclusion (Ranking Op-Amps at present(for me)):
1. still the Muses8920, but really tight behind-> ((update 2hrs later: i don´t get it; everytime i plug the Muses back-in again, i´ve got everytime the feel:“thats really hifi !“; such warmth+musicality..so „harmonic“ (must have something to do with the 2nd and 3th grade harmonics and so on))
2. LME49710; about 4-10% (IMO 😉 (more „clinical“+“contur“; has also its advantages))
3. OPA2134 (because of its „lively/airy attitude“)->10-15% back (to the LME49710)
4. LME49720 (for me a little bit to thin; but also very good in the „highs“) ->2%-5%
and very interesting would be how the AD797 were „performing“; i had an AD1988 as soundchip and as i hardly remember they were absolutely „sweet“ in the highs; never had such a fine resolution (mainly in the middle/highs)..
+ the „Bugatti Veyron“(->Link) of the OP-Amps, the OPA627 😉 ..
so, at present i will stuck with my „Muses8920“ although the LME49710s are absolutely close to them (maybe better in some „scope“)
greets for now 😉 (and thats all only my impressions; they are all very close and it depends really on your personal taste !!)
