    T-Class amp recommendations

    I am planning to buy a small T Class amp to go with a pair of Sinclair 40iX bookshelf speakers for my office. I see there is a multitude of these amps on EBay but I have no idea what is good and what is garbage. I will be using this with a Squeezebox(either a Touch or Classic) for my office. Digital out would be good but none of them seem to have this.
    Thanks

    I recently bought a SMSL Q5 Pro and am really happy with it. Digital and analog inputs, IR, sub out. Works with harmony. At about $120 it is more expensive than a Lepai, for me it is worth it.

    Tbh they mostly sound very similar. The cheaper ones used to have pretty poor analogue volume controls but now that's all digital frankly they are as interchangeable as DACs. For the money (i.e. not a lot), pick the one that has the features you need and looks nicest..

    I'm using the following in my office: Amptastic mini-T amplifier with a pair of small bookshelf speakers. I'm using an old Raspberry Pi with a HiFiBerry Dac. LMS running on a WiFi enabled WD MyPassport drive. This is fine for my purposes (I don't really run it at high volume!).

    Here's a picture (before I put it in my office!)

    They are so small you can buy the bare amp boards and mount them on the back of a speaker (or indeed inside) for an "active speaker conversion"..

    Personally Iĺd opt for a Class D amp.
    I have a couple of such amps from Topping that I use in the office etc. Build quality is good.
    VB2.4 storage QNAP TS419p (NFS)
    Living Room - Joggler & SB3 -> Onkyo TS606 -> Celestion F20s
    Office - Pi3+Sreen -> Sony TAFE320 -> Celestion F10s / Pi2+DAC & SB3 -> Onkyo CRN755 -> Wharfedale Modus Cubes
    Dining Room -> SB Boom
    Kitchen -> UE Radio (upgraded to SB Radio)
    Bedroom (Bedside) - Pi2+DAC ->ToppingTP21 ->AKG Headphones
    Bedroom (TV) - SB Touch ->Sherwood AVR ->Mordaunt Short M10s
    Everything controlled by iPeng

    Class T amplifier technology, so named because it comes from a company named Tripath. It's a trademark, not a recognized amplifier class; it's really just a variant of high-efficiency Class D (switching) amplification.

    Interesting article.
    The Topping Class D amps are definitely better built than the Lepai - Until recently I used one of mine with a pair of Mordaunt Short M10s as a sound upgrade on my bedroom TV. It worked very well but I have replaced it with something else now as I need more inputs.
    The other Topping drives a pair of Wharfedale Modus Cubes but more frequently a pair of AKG headphones by my bedside. It is fed by a Pi2 with iQaudio DAC (pCP).

    Ended up buying this off Amazon FX Audio D802C 80WPC Pure Digital Amplifier
    It seemed to have good THD, lots of inputs and didn't look bad
    I found this article comparing it with three other makes but it just added to my general confusion

    It is not a T-Class but is D-Class

    Most of the Toppings I know of are Class T using the Tripath 2020 or 2024 "chips"

    The TP-30 uses TA2024 and the TP-60 the TA2020

    As Slimchances says they are Class D amps but have DSP in the feedback loop as well as other enhancements.
