Hi,
Few days back while checking old stuff,I found LM1458N which I don't remember from where I got it.Just for curiosity,I checked its specifications and found that it can be used in ssp though they are not great-
LM1458N/NOPB Texas Instruments | Mouser
Just ran the system and found this op-amp very easy on ears.It was not only taking out details with ease,but not sounding harsh.Treble is sweet and well rounded.Instruments were well separated and have their own space in between.Background details were easily traced without need to find them.
Vocals and mids where it shines better.Vocals sounded natural and not to mention in the center.This opamp sounded neither laid back nor on the face.Its just played the music the way it should sound.
Bass is certainly present and goes deep easily depending on recordings.Yes the level of lows may be marginally low than rest of the frequencies.May be mid bass is little less.
The best part is you can easily forget speakers and enjoy the music.Feel of Saxophone, Piano was very realistic.Acoustic guitar strings appeals just the way you expect.There is hardly any congestion in the sound.
What I missed? The bigger sound stage.May be as said,mid bass have low levels and so the large sound stage can be missed.But in average room and with towers, this opamp can give a feel of real hifi for less price.I played on Bookshelf,also Tower speakers and so can conclude.
Comparing to DCB1,it has lesser sound stage say by 15%.DCB1 is more smooth,but this opamp sounded detailed.Also plus is the gain.
Coming to Burson opamp,observations same like dcb1.But burson can sound harsh occasionally with some recordings.Burson has more attack though.
Opamp 2134 is very warm compared to 1458 and instrument separation is not better than 1459.Yes sound stage of 2134 is bigger and laidback.
Lme49990 is the most silent in comparison.More musical than 2134.Good signature ,but some how I felt,other than soundstage,I did not miss anything with LM1458.
In short,if you get a chance to buy LM1458N for cheap locally,just try it.You might like it and the music can go step ahead without need of costly opamp.I can certainly say,Hifi sound(audiophile?) for lesser price with little compromise on soundstage.
Cheers.
