Resolut T-DSPmk2 Review: Resolut's Flagship Eight-Channel DSP, Explained
Updated: Oct 6
The Resolut T-DSPmk2 is Resolut's flagship eight-channel processor, which its maker describes as an ultra-top design without compromise. It combines an ESS ES9038PRO Sabre 32-bit DAC rated at 130 dB dynamic range with an Analog Devices ADAU1467 working at 192 kHz/64-bit, and Resolut quotes 140 dB signal-to-noise on the digital input. Its India MRP is ₹4,99,990, more than twice the price of the A-DSP, which has the same channel count and case size. It's built for owners chasing the last step in source quality from an already well-sorted system, including car audio competitors. Current pricing is on our T-DSPmk2 product page.
Quick summary
Eight outputs, as on the A-DSP, but with an ES9038PRO Sabre DAC rated at 130 dB instead of the A-DSP's 122 dB AK449X, and an ADAU1467 processor.
Coaxial and optical inputs are built in; analogue, USB, Bluetooth and MOST 25 inputs come from Resolut's plug-in modules.
Resolut's changes are concentrated in the conversion stage: an improved power supply, ultra-low-ESR capacitors and op-amps chosen for this DAC.
It costs ₹2,80,000 more than the A-DSP, and only a very resolving system is likely to show what that buys.

Figures come from Resolut's T-DSPmk2 page and its DSP Tool manual. The page's text still mentions the ADAU1466, but its spec table lists the ADAU1467, and Resolut's 2021 announcement confirms the mk2 moved to it. Resolut's catalogue card shows 140 dB as the dynamic range; we've used the spec table, which gives 130 dB for the DAC and 140 dB for the digital input. Our store listing differs from Resolut's published figures in a few places, and we've followed Resolut: it shows eight analogue inputs as standard, Windows-only software and a 50 mA Rem Out figure that predates the mk2.
What the extra ₹2,80,000 gets you
Resolut set out to build a processor without compromise, and the T-DSPmk2's upgrades are concentrated in the conversion stage. Resolut calls the ES9038PRO one of the best chips available today, and says it studied the weaknesses of existing high-end designs using this chip before building its own. The op-amps around it were chosen specifically for the ES9038PRO, the capacitors have ultra-low internal resistance, and the improved multichannel power supply has an increased number of supply lines, combining 1 MHz switching stabilisers with linear stabilisers.
The processor also changed. Resolut's 2021 mk2 announcement says it moved from the ADAU1466 to the ADAU1467, which has more input and output lines, improved coaxial reception and shortened the traces around the reference oscillator. The memory gets attention too: presets switch in real time, and Resolut rates the memory at a hypothetical 31,000 years even at 100 writes per second, a point it aims at competitors who retune constantly.
A sense of scale helps. The T-DSPmk2 weighs 1.6 kg against the A-DSP's 0.95 kg in the same case, and its converter figures are better on paper. But no independent measurements or listening tests were available to us, and converter differences at this level are tiny next to the road noise in a moving car. The gains Resolut describes are unlikely to be audible until speakers, installation and tuning are already excellent.
Inputs, modules and factory systems
Coaxial and optical S/PDIF inputs come as standard. Analogue sources go through the Resolut A-IN, which takes up to eight channels at line or speaker level. Resolut's page describes a summing mode for factory systems that recombines split analogue signals and compensates for the delays and phase shifts of complex factory audio. For digital sources there's the USB-IN HQ, the BT-IN with aptX Lossless and the M25-IN for MOST 25 factory systems. The SRC remote handles volume, subwoofer level, sources and presets.
Buy for what exists today. The T-DSPmk2 page still lists a USB and Bluetooth combination module, an HDMI module and MOST 150 as in development, so don't count on them.
Tuning with Resolut DSP Tool
The T-DSPmk2 uses the same Resolut DSP Tool as the rest of the range. The current manual lists Windows 10/11 and macOS 13 or later, four presets stored in the processor, Butterworth, Linkwitz-Riley, Chebyshev and Bessel crossovers, all-pass filters and 0.005 ms delay steps. REW measurement import is mentioned; automatic tuning isn't listed. A processor this capable is wasted without a careful measured tune, so budget for one. Our guide to setting up a DSP in your car outlines the process.
What owners and reviewers say about the Resolut T-DSPmk2
When we checked in October 2026, we found no owner reviews or independent tests of the T-DSPmk2. Its page at the Moscow dealer Magnitolkin says there are no reviews yet, and the Resolut listing at SoundDrive in Kazakhstan shows no ratings. Drive2, the Russian car community where installers post builds, blocked our access. Everything about sound quality above is Resolut's own, promotional description. If you've heard or owned one, we'd welcome your impressions.
T-DSPmk2 vs A-DSP, M-DSP and other high-end options
The Resolut A-DSP (₹2,19,990) shares the eight outputs, case, software and module options. It uses an AK449X DAC rated at 122 dB and the ADAU1452. For most systems it's the more sensible Resolut. The M-DSP (₹7,49,990) pairs two ADAU1467 chips with two ES9038PRO DAC blocks for 16 channels; Resolut says each block matches the T-DSPmk2's DAC implementation.
Outside Resolut, Zapco's HDSP-Z16 V AD-8A (₹2,49,990) is an eight-channel DSP with a built-in HD music player, an included Wi-Fi module, eight speaker-level inputs and a 3-inch touchscreen dashboard. It uses an AK4458 DAC as standard, and Zapco offers an ES9038PRO upgrade through its optional DAC Kit A. For everyday systems, JL Audio's TwK88 (₹79,990) does the core DSP job at a fraction of the price.
Who should buy it, and who shouldn't
Consider the T-DSPmk2 if your system is already built from high-end speakers and amplifiers, the car is properly damped, you feed the processor a high-resolution digital source, and you want the highest-rated converter in Resolut's eight-channel range.
Skip it if your source is a factory head unit with analogue outputs. The signal then passes through the A-IN's converter, which Resolut rates at 112 dB, so the case for the T-DSPmk2 is strongest with digital sources. Skip it too if the money would otherwise go on speakers or installation, or if you need more than eight channels.
Installation notes for Indian cars
The T-DSPmk2 is heavier than its size suggests, so fix it to a solid panel under a seat or in the boot rather than leaving it loose in the trim. Keep it well away from amplifier heat and direct sun. Resolut specifies 10–16 V for normal running and allows short dips to 6 V; a strong battery and good grounding help keep the supply steady when the AC compressor cycles at idle. Resolut says the mk2's Rem Out can switch several amplifiers directly. Route optical or coaxial cables away from power wiring. VA3 Car Studio in Ghaziabad provides professional installation and can tune the DSP.
Price and where to buy
The Resolut T-DSPmk2 has an MRP of ₹4,99,990. See today's price and availability on our T-DSPmk2 listing. Budget separately for modules: the A-IN and SRC are ₹44,990 MRP each, and the USB-IN HQ, BT-IN and M25-IN ₹54,990 each.
The bottom line
The T-DSPmk2 is Resolut's statement processor: the same eight channels as the A-DSP, with its changes concentrated in an ES9038PRO converter, a more elaborate power supply and the ADAU1467. It makes sense in a top-tier, digitally fed system tuned by a professional. For nearly everyone else, the A-DSP or a well-chosen cheaper DSP is likely to deliver most of the benefit for far less.
Resolut T-DSPmk2 FAQ
Is the Resolut T-DSPmk2 better than the A-DSP?
On paper its DAC is rated higher, at 130 dB against 122 dB, and it uses the ADAU1467 processor. Both have eight outputs and share software and modules. We found no independent comparison, and any difference depends on the rest of the system.
Does the T-DSPmk2 have Bluetooth?
Not built in. Resolut lists its BT-IN module, which supports aptX Lossless, as compatible with the T-DSPmk2. USB audio needs the USB-IN HQ module, also sold separately.
What changed from the T-DSP to the T-DSPmk2?
Resolut's 2021 announcement lists a move from the ADAU1466 to the ADAU1467, better coaxial reception, shorter traces around the reference oscillator and a higher Rem Out current for switching amplifiers.
