How useful are hifi reviews? We consider them useful for three things: (1) Surfacing new products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've ever heard (this means they probably are legitimately great). (3) Identifying a product's unique attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we  discount what reviewers say because they heap praise on everything—rarely being negative for fear of souring relationships with manufacturers. Further, they seldom have more than a couple products on-hand at once, relying on their imperfect memories to compare to past products.

  • Features the same DSPs as the MK2, enabling 20 PEQs per channel and active crossover management
  • Delivers incredibly transparent and exceptionally detailed sound
  • Easy to use, with browser or app-based configuration/control

Product Considerations

  • Upgradeability is limited to the HDMI section
  • Cannot be upgraded to a 24 or 32-channel unit, nor does it have the ability to install any digital input or output options available for the MK2 lines
  • The Dirac Live Base Control add-on is not included by default and is part of an optional license package
  • Auro 3D is limited to 7.1.6 speaker configurations

  • The ISP Core 16 uses the same DAC board as the StormAudio ISP Elite MK2
  • ISP Core 16 gives up some upgradeability options to achieve its less expensive price point compared to StormAudio's flagship ISP Elite MK3 processors
  • The ISP Core 16 is much lighter and smaller because it doesn't have as many legacy analog inputs

Takeaway: The ISP Core 16 offers great sound quality with an easy to use interface that can bring your home theater to life. Dirac Live and other technologies combine to deliver a fully immersive sound experience.

T+A

In the R 2500 R, the design and performance of our R series come together with the universal usability of a 'One Box System.' Its sources enable an almost limitless selection of playback options, with its integrated DSD and PCM converters transforming digital signals into analog signals of unique quality, which are then output to external speakers by the built-in amplifiers in T+A's typical sound quality. 

The new R 2500 R is among the first T+A devices to have access to the third generation of our 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. 

Measuring 16,5 × 46 × 40,5 cm, the R 2500 R follows our design philosophy of timeless reduction: Few but thoughtfully placed buttons interrupt the elegant front, whose characteristic phases create an almost seamless transition into the side panels, while the entire body of the R 2500 R radiates in the light gloss of hand-brushed aluminum.

T+A is a hifi brand that combines transistor and valve technologies in their HV-Series amplifiers, using high voltage for linear performance, while their A 200 Power Amplifier uses PURIFI Eigentakt technology for low distortion regardless of speaker load.

Our Summary

Product Strengths

  • Combines a CD player, FM tuner, integrated amplifier, DAC, and network streamer in one chassis
  • Features a minimalist industrial design and is made of thick-walled aluminum, with components machined from solid metal
  • Features a class-AB dual-mono amplifier design, outputting 140Wpc into 8 ohms or 250Wpc into 4 ohms
  • Has a DAC section with separate paths for PCM and DSD, using Burr-Brown devices for PCM and T+A's True-1-Bit converter for DSD
  • Features T+A's High-Frequency Sinusoidal Power Supply for stable power delivery

Product Considerations

  • The T+A MusicNavigator app was a bit clunky when it came to pairing the unit to a Wi-Fi network, requiring several attempts, but ultimately it worked
  • The app's search engine is not excellent, and interfacing with NAS libraries or attached hard drives requires more finger-punches to get to the desired music than the best streamer apps
  • The review unit had not yet been certified by Roon Labs as a Roon Ready device at the time of the review, though this may no longer be an issue

Comparisons (according to reviewers)

  • Vs MOON by Simaudio 390/760A—the MOON pairing had a warmer sound with greater focus on the midrange frequencies, slightly more guttural bass, and greater center vocal focus, but a higher noise floor on the phono stage compared to the R 2500 R
  • Vs dCS Bartók—the T+A DAC is like the sharpest HD photo, extremely detailed about the lines around things and the contrasts of sounds, while the dCS is always relaxed and musical, everything in balance always and a tiny bit 'impressionistic'

Takeaway: The T+A R 2500 R is a high-performance all-in-one component that offers many options for playing music from almost any source. Its build quality, powerful amplifier, and detailed sound make it a great centerpiece for a modern audio system.
