    Love these little TEACs to look at but haven't heard them. They seem to get mixed reviews.

    Anyone for the Sprout? How about the new Sprout 100? PS Audio has listened to customer feedback, made a few improvements, and bumped the power up to 100w/ch in the same package. They had it at AXPONA and it was pumping out an incredible amount of sound for the size! Paired with some ELAC UB5s, it would make for a killer "mini system" for a den or small room.

    Here's the new one:

    "Sprout 100"

    Would love to hear one.
    As far as I know, ICE-Power Class D modules are in play.

    Except Naim aren't Class D amps like some of the others, they are SS amps.

    "Timeless", yes, but the Nait 2 is 30 years old.
    The newest versions have a much larger footprint.

    Today I received this new Volt+D from India. Impressions to follow.

    All Class D amps are solid-state, aren't they?

    Class D is the PS used really. Hence why they are delineated from regular SS (class a and a/b).

    If by "PS", you mean power supply, then I think you're confusing "switch mode power supply" with Class D "switching" output configuration.
    Two different things. Neither dependent on the other.

    Class A, A/B, D...can all be configured to run off either linear or switching power supplies.
    Which is not to say that all amp designs will work well with either.

    I recently saw a Class A FET amp which runs off a laptop brick [almost bought it].
    Class A/B amps that use switching power supplies have been around awhile.
    Class D amps work quite well with linear supplies.

    In practice, yes. They are inherently analog devices so could be implemented using tubes.

    One of my tube preamps uses a SMPS while several of my diy class D amps use a linear regulated PS.

    and they don't sound like class D. They sound better, but maybe I just got unlucky with my chinese amps from ebay..:)

    There are excellent sounding Chinese class D amps and some that are good but less than great. Even the ones in the latter category sound better than the original T-amps which started the whole class D craze. This configuration of the TPA3118 ( Volt+ ) is the best I've heard but I haven't tried the Volt+D yet. Having massive iron in the linear regulated PS helps it rival many SET amps. The power supply is everything with these amps so if you're using a cheap lap top power brick you're not experiencing the amp's full capability.

    I don't know about the power supply, the guy at TNT audio who started the t amp madness said it doesn't matter much.
    I have some t amps and tpa3116, and one with some other chip. Listening at very low volume they are very good, the microdetails are great, probably because high power solid state like I have don't like to play at very low volume.
    I have a Topping T amp in the bedroom with some high efficiency vintage speakers, and I love it, but once I get it to the living room it becomes anemic..

    I ordered a Volt+ in clear case and it just cleared customs in Mumbai today! My reason for purchasing was that I want to give my Decware SE84UFO the summer months off.

    Poultrygeist, how does the stepped volume feel? Too stiff, not stiff enough, or just right? Thanks

    Onkyo mini amplifier made in Japan model A-905X has binding post on the back and sounds pretty darn good. Thought I would toss some semi vintage small form factor in the mix.
