TempoTec V6 Review (1) – Good, Better, V6!

The TempoTec V6 (full name TempoTec Variations V6 DSD512 Android HIFI Music Player) is a mature, great sounding player with all bells and whistles, offered at a ridiculously low price.

Pros — Rich, mature, refined sound; decent screen; dedicated line outs for balanced and single-ended; drives full-sized cans easily; huge 4500 mAh battery; great haptic; complete accessories; excellent value.

Cons — Does not pair well with with fringe iems (“current hogs”); only 16 GB onboard storage and a single SD card slot; volume knob a bit flimsy; computer performance mediocre.

Introduction

Tempotec has been delighting us with budget dongles in the past. The $40 TempoTec HD Pro may have stuck out as the best accessorized budget DAC/amp with all cables included (including Lightning cable for Apple devices). We also analyzed their BHD and Sonata HD II/Sonata E35 budget models.

The $279 (early bird; MRSP $399) TempoTec Variations V6 DSD512 Android HIFI Music Player is the company’s first mid-price digital analog player “dap”, and it is surprisingly way above the company’s usual budget realm. This raises the question whether the TempoTec can design a mature mid-tier player without the usual toothing issues.

What we don’t want to hear is reviewers saying “it is a good first effort, I am looking forward to the follow-up”…which would mean: stay away, save your $$$, and wait for something better.

Fortunately, this is not the case. The V6 is good, very good to be concise…and certainly good enough for me.

Specifications TempoTec V6

Physicals and Features

I am not known for my love of window dressing but the TempoTec V6 is presented impressively. In the box are:

1 x TempoTec V6 Digital Audio Player
1 x USB Type A to USB Type-C Cable
1 x Leather Case
1 x Screen Protectors
1 x Paperwork (Warranty card, Quick Start Guide, Manual, etc.)

A second screen protector is already (flawlessly) installed. Take this, Apple! The quality leather case is thick and robust, but a cut out above the microSD card slot would have been handy.

The player feels substantial in my hand. Great haptic, just like a much more expensive device. The button mechanisms are solid, just the combined on/off and volume knob has a bit of play owing to its spring mechanism.

Functionality and Operation

What it does

• plays music through single-ended and balanced headphone circuits
• has dedicated line outs for both single-ended and balanced circuits

What it does not

• 16 GB onboard storage is small

Hardware

The TempoTec Variations V6 DSD512 Android HIFI Music Player is essentially a phone without sim card, microphone, and loudspeaker, but with an audio component on steroids. The company scaled the computer part back in order to keep cost down. It features a basic Qualcomm Snapdragon 425 CPU and a 4.2″ 720 dpi screen.

The CPU is more than good enough for playing music, but not for playing games. The screen is fine for its intended use, too. It has a slightly warm tinge and is easy on the eye. The V6 features an accurate digital clock for removing phase noise in order to optimize sound quality.

In terms of DAC chips, the V6 sports two AK4493SEQ (no, the chips do not tell us anything about the sound, despite what the echo chamber in the blogosphere claims). The sound is produced by the DAC’s output stage and the amplifier.

TempoTec were initially not happy with the bass response and raised mid bass – which produces a slight bass boost and deviated the sound from neutral to mildly warm, still with good transparency.

The two dedicated line outs, one for balanced and the other for single-ended are a great feature that is usually reserved for expensive daps. I could handily connect the V6 to my desktop amp.

Software (Android 8.1; HiBy 3.0…)

Since the TempoTec V6 is essentially a small computer hosting the Android operating system, it can run (almost) any app from the Google Play store (and other sources). Due to the limitation imposed by the HiBy 3.0 player, the V6 runs 5-year old Android 8.1, whereas the current version is 12.

This could cause compatibility issues with some current apps, which is a problem for essentially ALL digital analog players – including the expensive ones. Another common problem is the lack of compatibility between Android and Apple. Mac users like me struggle with data transfer.

Bi-directional Bluetooth 5.0 is up to speed. As an internet device, the V6 was a bit slow on my mesh network (50 mbps download speed out of 150 possible on the 5 GHz band, Kazi reports 100/100 mbps on his single router; it also works at 50 mbps in the 2.4 GHz band) but this would be still more than adequate for streaming.

The HiBy 3.0 app is one of the standards across the board. Unique to HiBy is the MSEB, which stands for “Mage Sound 8-ball”. It is a parametric, very intuitive EQ. The OS also includes a standard EQ. Other remarkable features of the HiBy OS are low/high gain selection, crossfade, and antialiasing in the play settings.

Battery Performance

The TempoTec V6 hosts a 4500 mAh battery, bigger than in most phones. Interpreting battery drain is difficult as it depends on many factors additional to music playing, such as gain (high/low), equalizer use, volume, screen use, internet, Bluetooth, volume etc. After 12 hrs of continuous play with the 16 ohm/105 dB sensitivity Sonorous III headphone (low gain, with internet and Bluetooth switched off) at medium volume, there was 12% of battery capacity left.

I then charged it – and forgot – when checking after 4 hours the device was fully charged. After being switched off for almost a week, the charge was still at 98%.

Sound

The TempoTec’s sound can be characterized as slightly coloured, triggered by its somewhat boosted mid bass and its rather smooth, mellow/polite attack – which results in an analogish sonic perception with a timbre as close to natural as it gets.

Its balanced circuit delivers a big stage with a rather large headroom and an astonishing spatial reconstruction. The signature is very forgiving to aggressive recordings. I found the mature and balanced, well-dosed sound impressive from the first minute independent of pricing. It shows that TempoTec have obviously invested in their tuning.

The mid bass has more body than, let’s say, the discontinued $950 Questyle QP1R, but the V6 does not have that crisp leading edge. The V6’s notes are better rounded in comparison, the QP1R’s notes are better defined. The Questyle also offers more microdetail and better microdynamics.

In turn, the TempoTec V6 beats the QP1R in terms of staging and imaging. Which player is better is difficult to say as both are different beasts. Compared to cheaper alternatives, the V6 plays a league above my beloved $220 Sony NW-A55 and $180 Hidisz AP80 Pro-X in terms of refined presentation.

Where the V6 has problems is with “marginal” iems, such as current-hungry Final E5000, which results in a rather uncontrolled, muddy bass performance. Testing the TempoTec’s 4.4 mm balanced circuit with the 300 ohm Sennheiser HD 600 yielded great results. Swapping the HD 600 between V6 and MacBook Air/Fidelia player with Questyle M15 (balanced, high gain) came very close, sound wise.

Comparing the V6’s and QP1R’s DACs using the Burson Funk as amplification reveals the V6’s limits. The Questyle sounds more articulate with sharper notes, the V6 plays richer but not as detailed…though still pretty good.

In summary, the TempoTec V6 sounds enjoyable to my ears and we may have to pay a lot more to top it.

Concluding Remarks

The TempoTec V6 is a mature and impressive product. It is a fully fledged Android (internet) device, essentially a phone without sim card, speaker, and microphone. It may have a somewhat basic computer performance (to keep cost down), but it sounds very good, has impressive audio features (including dedicated line outs), and comes with complete accessories (e.g. quality leather case, installed screen protector).

At its very modest price, the TempoTec V6 is in its own class and will sell like hotcakes.

Until next time…keep on listening!
