The Opamp thread

I've already ordered the Bursons V5i and will try them on monday :beyersmile:

Maybe i order some SS3602 anyway just for fun. I only use the DX7 pro as my headphone amp so i only have to buy 2 of them and it's not too pricy :beerchug:

I was able to try the v6 vivid dual opamp out in my topping nx3s. All I can say is wow! It really opens up the soundstage. Everything got wider and I felt as if I could hear where each of the instruments were coming from. And it moved the singers voice just in front of me. The crispness it added to the treble and bass was incredible. The detail and clarity were amazing as well. This is all in comparison to the venerable ne5532 opamp which has been my favorite to this point. Unfortunately, this opamp is not practical for me. As you can see from the pictures you absolutely cannot have the amps case on and use this opamp. I really wish I could have fit it in my xDuoo XD05 plus, but it wouldn’t fit at all, even with the included spacer. If I had a desktop amp that I could use this one in I would in a heartbeat.

Have a look at the sparko op amps. They are flatter and might fit.

So you wouldn't change the OP Amps in the DX7 pro?

I've learned that sometimes the op-amp originally used in dac/amp is good enough and blindly swapping them doesn't bring any gain.
There are exceptions, of course. But what I mean is that the LME49720 is VERY good op-amp. I know the design is few years old but look at the Muses line - it is about same age (designed in 90's or ealry 2000's afaik) but still one of the best choices.

You wont be able to close the case with Sparkos anyway.

The M in Muses stands for Marketing. The Muses lineup is one of the worst sounding opamps of them all. Muses are all colored opamps, they change the sound in a significant way. If you are after transparency, avoid the Muses opamps imo. Muses opamps also have abysmal noise ratings.

Agree on the coloured part. I find Muses02 to be coloured but musical. Using 2x8920 in my modified ibasso amp1 module, and either these are more on the neutral side or the implementation in amp module doesn't show their character, coloured or not ;)
Haven't heard the rest.

But I know LME49720 and if there was hall of opamp fame one has to agree that it would be there (or 4562 or 49860). That was the point in my post :)

Thanks for the advice, I'll give rest of M series a miss.

Muses01 is the most uncolored and has the lowest noise. Muses02 is warm and is the noisiest. Muses03 has a focus on the midrange with an abysmally bad treble.

Burson V5i arrived a few minutes ago and they sound fantastic so far. Sound is much more smoother and pleasing with the DX7 Pro :)

Am i correct that the LPF Section in the DX7 Pro is just for Line Out?

My problem with V5i is the boomy and loose bass, just ruins bass for me
