    Sure. IIRC, Rockford Fosgate makes a tube AC-3 surround decoder and I'm sure they are not the only ones. But keep in mind that the actual decoding is still done with DSP chips. The tubes are typically used to amplify and buffer the output signals after they have been converted to analog.

    It isn't too difficult to add a 2 channel tube preamp to a home theater system, it is something I'm looking at right now. Some newer 2 channel preamps have an HT Bypass, that is routed around the gain stages and volume controls, directly to the output. But even it doesn't have a bypass you can still use a tube preamp with your HT system, you just have to work with 2 volume controls, the one on your digital pre-pro and the one on the 2 channel tube pre-amp. When you do your level calbibrations make sure you mark the volume setting on the tube preamp, so you can return it to the same setting every time you watch a movie.

    Sorry, I sometimes forget the name changes. The home audio side is now called Fosgate Audionics. Here's a link to the tube decoder I mentioned, the FAP-V1.

    Dan,


    if that's the case, why would they leave out DD/DTS?

    I see.. i guess it only accepts 5.1 analog inputs, and stereo inputs (which the DPLII DSP can play around with)

    I believe that back in the mid 90's ADA had plans to make a tube Home theater Pre-amp. It was shown in the early Home Theater Magazines and in the old video magazine. It had a thick glass face plate and had a window along the top window to allow for viewing the tubes. It was displayed in a similar way that car companies show off concept cars. I think it was planned to sold for 29000 dollars. I don't know if it ever made it to production, but it did look sweet. If can figure out how, I will scan the picture and upload it.

    Damn, I'm missing a few lately. There is or was a tube output AC3 processor a few years ago. I was thinking it was the Fosgate, but obviously that was wrong. It didn't do DTS because at the time DTS was not a standard feature. I had a link to the manufacturer, I'll dig around and see if I can find it.

    I recall seeing an all-tube pro-logic pre-amp, i think on SMR during one of their show reports. But other than that.....

    BTW, Rockford owns MB Quart, Hafler, and NHT.

    Danny, are you sure about that? I thought each of those brands, including Rockford Fosgate, was owned by Recoton.

    FeisalK,
    I do not think Robert was referring too DPLII as "antique".
    Although, it is, now that DPLIIx is here.
    I think he was referring to Tubes vs. Digital.
    To which I would ask him;
    Would you prefer to listen to first order or second order distortions?
    Do you prefer dry over liquid, in your audio presentation?
    Do you prefer electonic haze over detail?
    And, would you like your soundstage confined between the speakers or would you be more satisfied with a soundstage that expands beyond the speakers?

    Can anyone tell I am a Tube Fan???
