This power increase was targeted mostly at planars that are mostly current and not voltage driven (as opposed to dynamic driver headphones)

From a full 1 Watt of power on DX7s, newer device upped the game and delivers a whopping 1.7W in the same 32 Ohm impedance.

Another great improvement is the headphone amp section, DX7s was no slouch with headphones and could drive almost all of them except for current hungry headphones like low sensitivity planar-magnetic headphones.

DX7 PRO moved to 3 high-performance Accusilicon AS318-B femtosecond crystal oscillators, combined with a better DAC chip the total-harmonic-distortion (THD) was lowered by 5 times compared to DX7S! It sits at only 0.000084%, SINAD improved as well and on the XLR out it shows an impressive 121 dB, that is world class performance by my standards.

Probably the biggest change is moving from a dual 2-channel ES9038Q2M mobile DAC chips to a single but more advanced 8-channel and desktop class ES9038 PRO.

Bluetooth version 5.0 and the included antenna help a lot in maintaining a clear and stable wireless signal even with 3 concrete walls between the sender and the DX7 Pro

DX7 Pro has also an additional Bluetooth receiver, actually the best Bluetooth receiver as of right now (CSR8675 from Qualcomm), this one is capable of receiving AAC, SBC, aptX, aptX-LL, aptX-HD and LDAC for up to 990 kb/sec wireless transmission.DX7 Pro has an additional digital input – I2S input, from my listening tests this is the best digital input, closely followed by USB.It seems that DX7 Pro uses a slightly smaller and thinner case losing a bit weight in the process, it is now at only 1.4 Kg.So, if you are wondering what exactly was improved or changed or maybe left unchanged? Let’s take a closer look. Want it or not, Topping is growing fast and as far as I can tell their D90 will be the first commercial DAC with the flagship AKM4499 DAC chip inside.ĭX7 PRO is an updated version of the acclaimed DX7S that at that time replaced the DX7, as you can see DX7 PRO is the third iteration of the all-in-one DAC/Preamp and headphone amp combo, DX7 PRO has now even some powerful Bluetooth capabilities, should it also be called as a streamer? Not really, since both AptX-HD and LDAC are still not capable of delivering bit-perfect Hi-Res data streams, but in time with new tech that will surely happen. We already tested their D70 DAC and were impressed by its build, specs and measurements, but most importantly by its sound performance and incredible value.

I personally don’t mind waiting for a mature and polished product, I’ve seen multiple flawed devices (especially smaller portable ones) at their launch and nobody was happy with those.

At long last, after a long 9-month wait time of adjustments and tuning DX7 Pro sees the light of the day. In September we are assured no other delays will happen and that it entered final production stage. In January 2019 Topping announced that they are almost finishing their flagship DX7 PRO DAC and everybody prepared their wallets and some romantic stories for their wives, fast forward in April it was revealed that they are still tuning the DX7 PRO and are assuring a polished device with good specs and impressive measurements will come out of their labs.
