TEAC HA-P90SD Portable Headphone Amplifier/Digital Audio Player

TEACs HA-P90 is a high-resolution audio player and headphone amp for audiophiles on the go. A built-in microSD card slot can be loaded with high-resolution audio up to 192kHz/24-bit or Direct Stream Digital (DSD) at 2.8MHz or 5.6MHz. A high-end Burr Brown PCM1795 converter plays audio from the card USB input or from iOS or Android portable devices.

Audio electronics include Burr Brown OPA1602 SoundPLUS op amps dual sample clocks for 44.1k and 48k multiples discrete electronics and push-pull circuitry. A 170mW + 170mW headphone out is one of the highest-power amps available and drives loads from 8 to 600 ohms. The HA-P90SD supports WAV FLAC MP3 AAC DSF and DFF files either from the internal card or using the free TEAC HR Audio Player app for iOS and Android devices.

All of this great-sounding audio is housed in a robust all-aluminum chassis available in either red or black. With flexible audio format support – including DSD – and a powerful headphone amplifier TEACs HA-P90SD is the ultimate portable player for discerning listeners. 

TEAC HA-P90SD Portable Headphone Amplifier/Digital Audio Player Features:

High-resolution portable amplifier/player with DSD128 (5.6MHz) native playback

• The HA-P90SDs digital music player enables convenient portable enjoyment of PCM or DSD recordings (up to 5.6MHz) ensuring the ultimate sound quality even while on the move.
• Since debuting the TASCAM DS-D98 DSD-compatible professional recorder in 2001 TEAC has focused on the DSD format and DSD-compatible products. The DA-3000 Master Recorder released in 2013 supports the DSD128 (5.6MHz) file format and has come to be used by studios around the world to create high-resolution recordings in DSD and other formats.
• In the consumer audio field TEAC released the UD-501USB D/A Converter in 2012 which offers both DSD128 (5.6MHz) and PCM 384kHz native playback providing ready access to the high threshold sound quality of DSD audio file playback. The new HA-P90SD combines the dual functions of a high-quality portable amplifier and a DSD native-compatible player.

High-efficiency Analog Devices Blackfin BF606 processor

• Integrating both Analog Devices high-performance Blackfin processor—which features low power consumption characteristics—and an embedded OS help realize extended playback times of approximately 6 hours even when a high-resolution sound source requiring processing of large volumes of digital information is played back. This ensures the fullest enjoyment of high-resolution music files played back from a recorded microSD card.

Burr-Brown PCM1795 D/A Converter widely used in stationary D/A converters.

• TEACs UD-501 has consistently received high marks as a reference model for standalone D/A converters and both it and the DSD128-compatible TASCAM DA-3000 Master Recorder employ the Burr-Brown PCM1795 DAC which has been successfully employed by a wide variety of top-end equipment makers.

Master clock equipped with two crystal oscillators (44.1kHz and 48kHz).

• Two precise crystal oscillators are used in the master clock which plays a critical role in digital audio reproduction. The use of two dedicated clocks (22.5792MHz and 24.576MHz) for each of the systems 44.1kHz and 48kHz-multiple sampling frequencies enables perfect synchronization with playback file sampling rates and highly-accuracy D/A conversion. The HA-P90SD is also asynchronous-compatible and does not rely on the PC clock during USB digital connection. This high-precision internal master clock makes possible clear playback sound quality together with excellent jitter noise suppression characteristics.

Discrete headphone amp component design features op-amp with push-pull circuitry.

• The HA-P90SDs AB-class headphone amp features a discrete component configuration that utilizes an operational amplifier and push-pull circuitry. Technology accumulated during the development of TEACs HA-501 headphone amp was invested in this circuit design which achieves a 10Hz – 80kHz frequency range and a S/N ratio exceeding 105dB as well as 0.004% total harmonic distortion. Noise-suppression circuitry further ensures clear sound output conveying the finest subtleties of the original high-resolution sound source itself.
