    Tell your wife you will not buy any tube in the near future.
    Then you can secretly buy the batch linked in my last message. Ask the seller marked it as tools? on the box.

    Hey guys -

    Interested in experiementing with this aspect of the hobby. Any recommendations for a noob?

    I'd be curious to do a little more reading on this too so if anyone can point me in the direction of some literature that would be greatly appreciated too!

    Thanks in advance.

    421A slightly more power. Tighter deeper bass. But the 7236 is not that far behind. Then you have the 5998. finally the 6AS7.

    Anybody here powering desktop speakers with their Darkvoice? I see outputs on this thing, wondering how users here are using it if at all..

    You use it as a preamp output into your main amplifier. If you have a solid-state power amplifier that sounds a little bright or harsh to you, you could warm it up and soften it by using the dark voice as a preamp . If you did try to power a set of speakers they would have to roughly be 100db or more efficiency to take it vantage of 1 W or less of power, not only that the dark voice was meant for higher impedance headphones . Not low impedance four ohm or eight ohm speakers

    So the Darkvoice 336SE is now available on Massdrop. I've never used a tube amp before. What should I expect compared to solid state amps? I'd be powering HD6XX and 58X headphones.

    Buying some NOS (New Old Stock) tubes right away would be your first experience. A nice warm sound with added bass and width to the Sennheisers. Because of the high impedance of the two cans you have, the Darkvoice will excel in driving them because of it's OTL (Output Transformer-Less) design, almost made just for the Sennheiser. reading back 20 pages (here on this thread, heck, read from page 67 and on) will save you a lot of monies towards tube choices. And the Massdrop Discussion group has a lot of info too. We can also recommend tubes for ya to begin with.

    I doubt the Darkvoice 336 has enough power for speakers unless they are powered. However, I have been enjoying using the Darkvoice 336 as a preamp for my amp + speakers so much that I retired my regular preamp. In my setup

    PC->DAC->Darkvoice 336->amp->speakers

    Darkvoice 336 produces a detailed, warmer, spatial music presentation, much better enjoyable than my other solid state preamps.

    Just got myself a 336se. Should be here next week. I previously had a Little Dot MKii which I foolishly sold off despite having collected some very nice tubes for and I've been missing it for my 6xx. Instead of rebuying I decided to try something different.

    I've already won auctions for a red label RCA 6AS7G and an RCA 6NS7 grey ladder to get started.

    Any recommendations for some "must try" tubes for this guy? I'm wondering if there equivalents to some of the "must trys" for the LDmkii (Voshkod EV, GE Jan 5654, Mullard 8100, etc).

    Any advice to first time owner would be much appreciated.
