T+A Audio R 2500 R Multi Source Receiver and CD-Player

Just add speakers! A 180Wpc receiver with a range of digital sources, including CD, streaming, and wireless. With FM radio and headphone out.

T+A's R series takes concepts, circuits, and technologies from the flagship HV range and present them in a smaller, more inexpensive line of products.

Although the R-series cases are significantly smaller than HV, T+A has succeeded in realizing very high output power. The amplifier stages are of discrete construction, and are based on the HV principle, making them extremely linear, with a very wide frequency range and outstanding transient response. Since one aim was high output power, T+A developed a mains power supply of extreme efficiency, capable of remaining totally stable even when handling peak loads. Therefore the bass reproduction is incredibly precise and controlled no matter what loudspeakers are used.

A Universal Playback Device

The multi-source player is T+A's universal playback device, based on the technology of the HV series, equipped with a high-quality CD transport and able to cope with a range of digital music formats. The converter section the unique T+A True 1-Bit DSD 512 and 384 kHz PCM.

The new R 2500 R is among the first T+A devices to have access to the third generation of the German company's streaming architecture: It not only allows access to streaming services and USB sources but, for the first time, a T+A device can be controlled directly from the mobile streaming apps Spotify and Tidal via Connect Services.

The DAC Side

The T+A True-1-Bit converter used in the R 2500 R is notable in that it does not convert DSD to PCM, but is a true 1-bit converter. This means processes DSD files natively without harmful conversions and reproduces them absolutely unadulterated in the true 1-bit stream.

On the PCM side, the T+A Quadruple converter is a doubly symmetrical circuit with eight 32-bit Burr-Brown converters to compensates for sonic nonlinearities and reducing the already minimal noise by an additional 6 dB. This effort results in astonishing linearity and dynamics with equally impressive distortion-free clarity.

There are six oversampling filters that set different time domain or frequency response behaviour for each individual filter. The T+A True-1-Bit converter features two different converter modes for DSD playback.

The Streamer Side

T+A's Audiophile Streaming Architecture (ASA) maximizes sonic potentials and source diversity, offering WLAN, LAN, and USB inputs. The R 2500 R can access streaming services such as Deezer, Qobuz, and Tidal and also local network files up to 384/32 (HD) as well as incoming streams from mobile devices via Connect or AirPlay. It can also play uncompressed FLAC files via aptX HD Bluetooth. DSD files are streamed to the T+A True-1Bit converter.

The Amplifier End

The T+A High-Frequency Sinusoidal Power Supply provides large amounts of current with great dynamic ability. Built completely dual mono, there are two identical separate amplifier circuit boards – with input section, volume control, high-voltage amplifier and current amplifier, so that the sound quality of both channels is identical.

As with our HV-series machines, the circuit topology of the input stage is based on a cascoded differential amplifier with hand-selected audio J-FET transistors and stages of completely discrete construction, without operational amplifiers (op-amps). This overall circuit design, combined with the high quality of the components employed, virtually eliminates the need for overall negative feedback. The result is that the amplifier boasts excellent linearity combined with an extremely wide dynamic range

The volume control takes the form of discrete precision resistors and bi-stable gold-contact relays, resulting in absolutely exact channel matching combined with the shortest possible signal paths; this in turn virtually eliminates noise and distortion. The following voltage amplifier stage and current amplifier are completely isolated from each other galvanically. This uncompromising design completely avoids the danger of feedback effects from the loudspeaker currents into the voltage amplifier stages, and also precludes adverse effects from the loudspeaker load.

The amplifiers are fitted with separate tone controls for each channel, and the function can be completely by-pased by means of gold-contact relays. A loundness circuit is present which can be adjusted to match the efficiency of the loudspeakers.
