Primaluna separates or Integrated?


Im planning to upgrade my system around a recently purchased gorgeous sounding Primaluna CD player and my trusty 25+ year old Linn Sondek LP12 turntable. I am very interested in experiencing Primaluna amplification and am interested in advice of which route to take of either the Dialogue Premium Integrated or the Prologue Premium separates. I admit that I have not had the opportunity to listen to triode vs. ultralinear which seems to be the most significant difference between the two options.  Thoughts and opinions?

@ezstreams,

Thank you for the nice words :-)

I have no way of knowing if a similar problem would arise if a different PrimaLuna model than the OP was using in the thread I linked to were to be used with your Tritons. But it wouldn't surprise me if there is enough design commonality among PrimaLuna's various models for the problem to arise.

On the other hand, though, should that occur it seems to me that the resistor solution would be a good one. The only downsides I would expect are a slight reduction in the maximum amount of power that could be delivered to the speakers, and perhaps a tiny increase in distortion due to the slight reduction of the overall load impedance seen by the amp. I'd be very surprised if either of those effects were great enough to be audible.

I should mention also that if you were to go with one of the higher powered PrimaLuna models the 47 ohm 12 watt resistors that were used by the OP in the other thread with his approximately 40 watt amp may have to be different in one or both of those parameters.

Good luck, however you decide to proceed. Best regards,

You will find the following thread to be of interest:

https://forum.audiogon.com/discussions/primaluna-prologue-integrated-help-needed

As you’ll see, the OP in that thread had a problem using the PrimaLuna ProLogue integrated amp with his GoldenEar Triton Two speakers, in the form of a "throb" at about two beats per second that occurred when the volume was raised beyond a certain point.

Like your Triton Three his Twos have internal amplification for the deep bass, resulting in an impedance that rises to very high levels at deep bass frequencies. And it turned out that the amp wasn’t happy working into a load that was essentially absent at low frequencies. The result being what is referred to in electronics as "motorboating."

I suggested that he try putting suitably chosen load resistors on the output terminals of the amp, and that resolved the problem.

Good luck. Regards,
