Are you talking about the "voltage pots" on a discrete Op Amp?

 

If you are, then you are probably hearing more distortion, less distortion.

Some of the pots may affect DC offset, you really don't want to adjust those, unless you want to reduce DC offset.

 

Note to Mr. "I Love Music":  an Op Amp should take approx. 1/2 an hour to warm up.

 

Well, since I am far from an electrical engineer, I definitely don't understand amplifier design at all. Seems like you volunteered for it :)

 

Here's what I am referring to. Found it in the old Roc thread, couldn't find the phoenix one.

..i believe that any new part in the amp has some burn in time..but there are others who disagree..like saying that an SS amp dont need burn in time...i gsve my opamps 627 time to burn in..its up to u to do it or not...wink.gif

For the price, I think the M-stage is a superb amp. Currently driving my HD650s with one. I'm planning on upgrading to something like a Musical Fidelity M1 as soon as my wallet approves, since I'm not 100% happy with my setup at the moment. But since I got the M-stage for less than $140, I really can't complain much.

They should change the voltage in circuit. Wayyy back when I had a Roc and Phoenix from Audio-gd changing the voltage drastically afftected the sound overall.

Hey, I'm not too sure what this has to do with the Matrix M Stage?

 

When you tweak those pots, you are probably just increasing the distortion.

In theory, the pots should have been factory set for minimum distortion.

 

A "brighter, snappier" sound probably means more odd order harmonics.

A "warmer" sound usually means more even order harmonics.

 

I'm sute this is what we are doing when we start rolling tubes in tube amps!wink_face.gif

 Matrix is a superb amplifier at any price wink.gif but unfortunatelly I feel it doesn't play so well with HD650. MF X-Can V2 and V3 are, in my opinion, a better match to HD650. I don't know about M1 HPA but am interested in opinions from anyone who has tried that setup.

I on other hand thought the HD650 paired really well with M-Stage

I mean it is not bad but x-can gives a little more sparkle to HD650 and even to DT880/600.

Well i guess i then prefer super order harmonics in my amp over no harmonics and listening to a heartless cold ear destroying sibilant amp then...like a o2. Imhobiggrin.gif

As in sparkle do you mean treble? Cause treble extension is one thing I tried avoiding when looking to pair the HD650 with an amp. But maybe some will find the pairing too soft and warm.

 

I guess the X-Can is generally brighter than M-Stage if I understand it correct?

I've never really liked the M Stage with DT880/600.
Sounds kinda bland.

Anyone know if the LME49990 opamp is worth the upgrade to stock for the m-stage v2?  I'm thinking of having it modded with the LME49990 opamp to pair with my DT 990/600 Ohm headphones.

I don't know much about the LME49990, but the LM4562 has a lot of fans here, including me.
