Jm Lab Alto Utopia what kind of amplifier ?

Our customers report good results so I think its safe to say that the JM Labs speakers do well with tubes.

If you are looking for solid state, I have heard Rowland work well with JMLabs Utopias.

Hi Zszwedo,

I had very good experience with Accuphase and Musical Fidelity (MF). A MF
integrated like KW-500 or KW-550 will be a very cost effective solution.
However, your choices are probably endless, e.g. Graaf, Jadis, ASR, Pass Labs,
YBA, Rowland, etc. I agree with Atmasphere that the Altos sing very very nicely
with tubes.

I think you are right about tubes Atmasphere, I just have no experience with OTL amps and I'm not sure about the looks of Atmasphere amps. I wish I had a store nearby to listen to these. Thanks
