I had them in a 15'x19'x10' room high passed to a pair of Vandersteen subs at 80hz. Even with the burden of the bass regions removed from the main amp the lowest powered amp I ever felt comfortable with was the Music Reference RM-10 at 35 wpc. So unless you are in a much smaller room or listen at "background music" levels I am not sure the SIT-3 is going to be enough to suit you in the end. If you haven't you might want to talk to Bob at Amherst Audio about amp matching with the Offrandes. He personally had a pair for over 15 years and may still have his even though they were discontinued last year. He favored driving them with hybrid's if I remember correctly probably Blue Circle and also Audiomat. I have their "little brother" the Twin Signature in my Office system and drive them either with the RM-10 or a Kora hybrid integrated.

    Also don't know when Jean Claude started listing them a 8 ohm speakers as they and most all of his father's designs were 4 ohm speakers.
    Yes, the Offrandes do indeed make for great listening. Sadly they have been discontinued and the current version is the last.

    I am actually driving them with a 10 watt per channel tube integrated at the moment with fine results. My room is fairly small, 13' x 20' or so, and I listen at low to medium levels. However, I am pretty sure my little 10 watt DIMD PP10 has more than 11.5 db of gain. Hence my curiosity about what pre-amps to look at.

(The formula for parallel resistances is to multiply their resistances and then divide the result by their sum, so for this example: (8 * 8) / (8 + 8) which is 64/16 giving you a net 4 ohm load.) While the amp would then deliver its 4 ohm power rating, half of that would be going through the resistor and not to the speaker. So in addition to taking into consideration whether the amp may sound better driving an 8 or 4 ohm load , you would only get 15W of the total 30 available to the speaker.
    Thanks for the explanation. Not an option then.

    Re: FirstWatt SIT-3

    In his 6Moons review of the SIT-3, Srajen easily drove the the amp with the STP-SE into a much larger room as did Joe so I don't think you would have an issue. I have owned an STP-SE for over five years and not encountered an amp it wouldn't drive and never come close to engaging the active section.

    Re: FirstWatt SIT-3

    Iím running the SIT-3 with the VAC Master Preamp and itís just incredible. This amp is like none other. It doesnít sound tube or solid state.

    I tried it with the ARC REF6 and it was a mismatch. Normally, ARC Preamps with Pass amps are great. But this was not ideal.

    So, I think the preamp matching with this amp is key.

    Mike,
    Any idea why it did not work well with the ARC preamp?

    Mike,
    Thanks for the explanation. In your opinion, apart from the Avantgarde speakers, are there any other speakers that would be an ideal match for the SIT 3 amp?
