What to put between a Calypso a Mini Utopias?


I have been trying to develop a "short list" of amplifiers to evaluate. My preamp is an Aesthetix Calypso and my speakers are JM Labs Mini Utopias.

There are many glowing reviews about mating an YBA Passion the Mini Utopia, but I'm not looking for an integrated amp solution at this time. I am committed Calypso.

The Mini Utopias are 91.5 dB efficient and JM Labs recommends an amp no higher than 150W. They are only capable of low frequency down to 39Hz. I use a sub to help shore up the bottom end.

Stereophile said “the Calypso will need to be used with a power amplifier offering an input impedance of at least 30k ohms if the bass is not to sound lean.”

In terms of cost, I suppose I would like to come in under $5K, but I wouldn’t hesitate to increase the budget if the sound quality warranted it.

Any experiences or ideas would be greatly appreciated. BTW, solid states, tubes, doesn’t matter to me either way. It's all about the music. Fussing with equipment doesn't bother me if the end justifies the means.

Thanks

Hi Buckr,

Hah! Just came across this sequence of conversations. I guess I didn't know you were thinking about the CJ 140 monos...then you got that beauty of an amp from me. How you doin'?
