The Transaudio D5 Pro has generated a lot of chatter across Hi-Fi forums and video reviews as a surprisingly affordable power amplifier coming out of China. Positioned as a direct clone built upon the circuit topology of the famous darTZeel NHB-108 – a legendary Swiss ultra-high-end amplifier costing tens of thousands of dollars—the D5 Pro promises a taste of luxury sound at a tiny fraction of the original’s price tag.
Price & Key Specifications
On the secondary market and direct import channels, the Transaudio D5Pro Power Amplifier generally retails around $900, depending on seller options, shipping location, and standard vs. upgraded component trims.

Technical Concept: Transaudio D5 Pro vs. Original darTZeel NHB-108
The original Swiss darTZeel NHB-108 gained iconic status for its unique open-loop design philosophy, using zero global negative feedback to eliminate transient intermodulation distortion and preserve organic musical timing.
The Transaudio D5 Pro attempts to mirror this circuit design. However, the deliberate absence of global negative feedback dramatically impacts performance metrics—most notably output impedance. This significantly reduces the damping factor of the amp (around 24), lowering speaker control to a level that is below even many traditional tube amplifiers. While this approach aims to deliver an unconstrained, fluid musical character, it places unique demands on speaker pairing.
Even across different loads—trying it with 4 different sets of speakers, ranging from demanding 4-ohm floorstanders to easy-going 8-ohm bookshelf speakers—the core sonic sonic traits remained very similar.
Sound Quality & Performance
The Warm & Rich Character
Right out of the box, the D5 Pro presents a unmistakably warm and rich sound signature. Notes carry an extra layer of body and lushness, giving vocals and acoustic instruments a smooth, rounded presence that avoids harshness or listening fatigue.
Bass Performance & Dynamics
Despite the low damping factor, the lower frequencies are surprisingly strong, fast, and dynamic. Bass lines have decent pace and momentum. However, don’t expect it to match the control or slam of truly great solid-state powerhouses—it simply isn’t there. The ultimate sub-bass control and visceral physical impact fall short, leaving complex or fast low-end passages feeling slightly soft around the edges.
Soundstage & Transparency
When evaluated alongside reference gear—such as an **Ayre V-3** or even a venerable **McIntosh MC275** tube amplifier—the D5 Pro shows its limitations clearly. Compared to these classics, the Transaudio runs very warm sounding, losing a significant amount of micro-detail and upper-midrange transparency. Where the Ayre and McIntosh create an expansive, three-dimensional acoustic space, the D5 Pro offers little holographic soundstage to talk about. Images remain relatively flat within a narrower field.
Final Verdict
The Transaudio D5 Pro is, on its own terms, an undeniably pleasant-sounding amplifier. It delivers a relaxed, full-bodied presentation that makes for comfortable long-term listening without any metallic glare or grain.
However, it ultimately lands as a bit of a disappointment. Based on the overwhelming enthusiasm in many online and video reviews—and given that it claims such a prestigious circuit pedigree—expectations were set high. While it offers solid chassis construction and good value for a budget solid-state amp, it does not truly capture the magic, micro-dynamics, or spatial precision of the high-end amplifier it seeks to emulate.
Hi,
From the chinese clone speaker amps you’ve tested, which model do you recommend for the budget one? I’m looking into the chinese clone amp and don’t know where to start.
The best one for that would be Burmester 909 clone. The bass is unbelievable on that one. There are currently sales on Aliexpress (you can get it for around $1200 all included – search for BL-9 T9.4 HI-END). The next up would be Accuphase Clone SU550 (available on amazon), not as good as Burmester, but still very good. Last but not least is Transaudio T11 Pro (that thing is a true beast, but expensive around $3K)
Thanks for the advice! If budget is the only concern and I don’t care about which sonic characteristic it prioritizes, which one would you recommend?
Then go for class A, it will give you a tight bass and even something like Musical Fidelity A1 clone would work if your speakers have 90+ DB sensitivity.
Hi,
Continue from the conversation above (can’t find the reply button from there, sorry), I have ELAC DBR62 which has sensitivity of 86db. So, the Musical Fidelity A1 clone won’t work with it, right? Which budget Chinese clone amp would you recommend then?
(Sorry if I ask too much, just a beginner here. Thanks in advance!)
So, if you have any experience or educated guess, would the supposed upgraded D9Pro Master edition clone be of similar performance as the D5 Pro?
I tried the A1s clone & would say for the ultra budget price of the amp yet paired with a pair of my more expensive yet easy to drive bookshelves (Fritz REV7 SE) it’s an ok amp. I guess for $250 it’s a good amp.
Is something like a $1k clone worth the money (& risk)? Curiosity is getting the better of me & I would like to know. I do have access to more expensive & established brands to compare to. It’s hard to trust or get a gauge on reviewers who think these products are great… but they don’t have the experience or reference to compare these amps to.
But I guess if an amps weak link is that it’s softer or lusher thru the mids & highs it could at least be fun for certain genres..or maybe exactly what some people are looking for.
D9Pro would be very similar to D5Pro, since they are based on the same schematic, just more voltage on power rails and more output transistors to deliver more power (if you need that). Recently, we tried D5Pro with La Scala that is said to be great with tube great, and it is, but D5 did an outstanding job even compared to AVA 400R and Ayre V-3. I would put it against any modern amp under 3-4K in the states. So that’s a fantastic result. When compared to PS Audio BHK 250, it clearly lost in practically all aspects, but that’s a 4K amp used. So don’t expect a miracle, but it’s a fantastic amp that delivers way more than what the price suggests.

Hi,
From the chinese clone speaker amps you’ve tested, which model do you recommend for the budget one? I’m looking into the chinese clone amp and don’t know where to start.
Thanks!
What is the most important aspect of audio is for you? Tight bass, liquid midrange or sweet transparent top?
I think it’s tight bass.
The best one for that would be Burmester 909 clone. The bass is unbelievable on that one. There are currently sales on Aliexpress (you can get it for around $1200 all included – search for BL-9 T9.4 HI-END).

Nope, Musical Fidelity A1 is a no go with those speakers. I would recommend D5Pro. That would give you great bass for a very good price.
