For those interested in the PrimaLuna Prologue One

I'm currently breaking in a Prologue One in my reference system (and I've also used Tylers Linbrrok Signature one piece system). I'm posting this because of the review in The Absolute sound which was very positive and minimized the value in rolling small tubes......they didn't mention the power tubes.

I found this amp to have a severe lower midrange suck out with the factory tubes using both sets of speakers and using both 4 and 8 ohm taps. The mid range was good, the bass was very good for such a small amp, but there was no connection between them. I changed the power tubes to Svetlana - absolutely huge difference!!!! The whole frequency spectrum is now there. Very nice sound now, especially for the price. Small tube rolling next.
