PrimaLuna DiaLogue Tube Power Amplifier w/ Lsi15s

Hi Folks,

I was thinking of going the tube route for a main amplifier. Currently I have a SS amp powering two Lsi15s (music/HT). I was hoping to see if anyone had any experience with the PrimaLuna line. I see that they are rated for 4ohm but not sure if they would have enough wattage to power the Lsi15s properly.

TIA

    I heard a PL with some Martin Logans. It was sublime! I was actually considering (someday) picking up a pair of their Prologue mono's. https://www.primaluna-usa.com/prologue-premium-mono-power-amplifier

    I have some comparable Monoblocks I am selling from ank at similar power ratings. 40 watts on the EL34 would definitely power the lsi15

    Didn’t like my Primaluna Prologue Five driving my Martin Logan Electromotion ESLs. 😬

    I don’t consider them to be very hard to drive either. B&K ST125.2 drives them with ease, only gets mildly warm.

    IMO/IME, PrimaLuna amplifiers sound best when driven by their matching tube preamps (or other similar quality tube preamps), rather than solid-state in front for source and preamp.

    Years ago, I purchased the Primaluna Prologue Five with the same idea in mind; but in retrospect, I would have rather started with a good tube preamp driving a decent solid-state amp to get that bit of warmth/sweetness/humanity.

    Then adding a tube amp afterwards increases palpability/warmth/juiciness/texture/soundstage. The combo of tube pre/tube amp expands everything and some people like it; others feel it can be too much of a good thing; and others still, like it as an alternative, but maybe not day in / day out.

    I would recommend going for a tube pre with HT bypass if you want some tube flavor; PrimaLuna would be a great option for this still.

    Don’t know your amp, but as long as it is rated to drive 4 ohms, that is a better fit for LSi15, IMO, since they are current hungry speakers.

    @acmf74 - I would add that while a tube amp may power your speakers, you will want to be mindful of the impedance variations of your speakers.

    Impedance matters when talking tube amplification and speaker matching!

    If the impedance of your speakers rises in the upper mids/highs, this will result in a forward (potentially bright) sound, which is usually opposite of the reason that people get into tubes.

    Good luck.

    Thanks for all the replies.

    Currently I have a Mark Levisnon No27 amp for the front two speakers (Lsi15) and a Rogue Perseus Magnum preamp.

    Some of Rogue amps/Mono blocks piqued my interest too.

    I haven't heard that amp but it may not be a step up. Probably more of a change in flavor.

    Good to know.

    Even though you have a tube pre, I would still lean toward solid-state amplification on the LSi15s; however, if you do introduce a tube amp, I would keep things in the Rogue family, rather than PrimaLuna.
