Underneath it is thoroughly modern: streaming, conversion, amplification, radio and a phono stage in a chassis 100 mm tall weighing 6.2 kg. See the \u003ca href=\"https:\/\/shop.martinshifi.co.uk\/collections\/t-a\"\u003efull T+A range\u003c\/a\u003e we stock.\u003c\/p\u003e\n\n\u003cp\u003eWhat makes it interesting is that T+A have not simply bought in a streaming board and an amplifier module and put a nice case around them. The converter section is the same two-path thinking used further up the range, and the amplification is Class-D chosen on merit rather than to save space.\u003c\/p\u003e\n\n\u003ch2\u003eAmplification\u003c\/h2\u003e\n\n\u003cp\u003eThe Symphonia uses \u003cstrong\u003ePURIFI Eigentakt\u003c\/strong\u003e Class-D output stages fed by T+A's own High-Frequency Sine Power Supply. It produces \u003cstrong\u003e250 watts per channel into 4 ohms\u003c\/strong\u003e and 125 watts per channel into 8 ohms to the FTC rating, with a damping factor above 800. That damping figure is the number to note — it is the amplifier's grip on the loudspeaker, and it is why the Symphonia drives real loudspeakers rather than only the easy ones.\u003c\/p\u003e\n\n\u003cp\u003eA \u003cstrong\u003eDigital-Analog Separation System\u003c\/strong\u003e using Silicon Labs isolators galvanically separates the digital and analogue sections. In a box this size, with a switching amplifier and a network board a few centimetres from the analogue stages, that separation is doing necessary work.\u003c\/p\u003e\n\n\u003ch2\u003eConversion\u003c\/h2\u003e\n\n\u003cp\u003eAs elsewhere in the range, PCM and DSD get their own converters. PCM runs through a \u003cstrong\u003eDouble-Differential-Converter\u003c\/strong\u003e with 32-bit Sigma-Delta conversion at 705.6 \/ 768 kSps; DSD goes through the \u003cstrong\u003eT+A True-1Bit converter\u003c\/strong\u003e as native bitstream. Selectable upsampling algorithms (FIR short, FIR long, Bezier\/IIR) sit ahead of a phase-linear third-order Bessel filter switchable at 60 or 120 kHz.\u003c\/p\u003e\n\n\u003cp\u003eWorth being precise about the DSD limits, because they differ by input: the USB DAC input accepts up to \u003cstrong\u003eDSD 512\u003c\/strong\u003e, while network streaming covers DSD64, DSD128 and DSD256.\u003c\/p\u003e\n\n\u003ch2\u003eStreaming, Radio and Connections\u003c\/h2\u003e\n\n\u003cp\u003eStreaming runs on T+A's \u003cstrong\u003eASA G3\u003c\/strong\u003e architecture over Wi-Fi, wired LAN or USB. Services covered are Tidal, Qobuz, Deezer, Amazon Music HD, Spotify Connect, Roon Ready, Audirvana and JPLAY. T+A list Apple AirPlay as under certification, so treat that one as pending rather than confirmed.\u003c\/p\u003e\n\n\u003cp\u003eBoth FM and DAB\/DAB+ tuners are built in with RDS — increasingly rare at this level and a genuine reason to choose it. Digital inputs are coaxial and optical S\/P-DIF, USB DAC, and one HDMI input with ARC for a television. Analogue inputs are two line-level RCA plus a third with a switchable phono stage. Outputs are a preamplifier RCA out and two subwoofer outputs.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOutput power (4 ohms)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e250 watts per channel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOutput power (8 ohms)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e125 watts per channel (FTC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAmplifier topology\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eClass-D, PURIFI Eigentakt, High-Frequency Sine Power Supply\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDamping factor\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u0026gt;
