Visit my blog for the latest edition/score of the TC-7510 MKIII review.




My new Beresford TC-7510 MKIII is finally here! I've been burning it in for a couple of hours, and I am extremely impressed. Below is my initial impression of this DAC and some pics!

Construction (9.5 /10)

The TC7510 was extremely well packed and was double boxed in 2 white boxes. Opening the box reveals a neatly packaged DAC with the power unit. The dac feels extremely solid and compact. One of the reasons why i purchased the Beresford over the Zhaolu is because of its size. Measuring only 12cm x 25cm x 4cm, the Beresford was the only option over the Zhaolu in its price range since i needed a desktop equipment. All the edges and corners are well rounded and smooth, and the gaps are seemless. On the front panel, there are 5 shiny little buttons with a LED that displays GREEN when on and RED when standby. It never actually shuts off unless you take out the power. To the right is the headphone jack and its volume control. In the back, there are 2 sets of RCA output, and 2 sets of optical and coaxial input (total of 4). In all, the look and feel of the DAC gives me a very professional feeling.


Line-out Sound (8.5 /10)

I tested the line-out through an optical connection. In this review, I will cross-reference with my currently owned Creative Audigy 2 ZS Notebook Soundcard (not the PCI version, their sounds are very different, the Notebook version is more superior). Two methods of testing the sound of this DAC were commenced.

First, a [RCA male to 6.25mm female jack] adapter was used to directly connect the line-out to my headphone. By doing this, I am able to skip the amp's influence and directly test the sound coming from the Beresford. For headphones, I used a 50ohm Sennheiser HD595. The HD595 is famous for its revealing character. As such, any bad recording or bad equipment will negatively reflect into my ears. The initial impression of line-out sound is extremely positive. The sound appeared very detailed and transparent. Each note was very accurate throughout the frequency scale. Bass notes were also very accurate and clean. However, I'd like to see the bass hit lower. The TC-7510 appeared rather neutural: neither bass-oriented nor trebly bright. Any defect in the recording was immediately noticed. The soundstage was also very decent, much larger and fuller than my Audigy2 ZS Notebook. However, because of its neutral quality, sounding neither dark nor bright, it conveyed a sense of dullness. Perhaps that is what people are looking for in a DAC? Neutrality could mean bad for some, while meaning very good for others. So, it depends on how you see it. What I would like to see, however, is for the low mids to become more apparent. That was the only thing i believe, to make the TC-7510 an exceptional DAC.

Second, a generic male RCA to RCA cable was used to connect the DAC's line-out to the line-in of a tube amp- Little Dot II++. That was when magic happened. Initial impression was

. All i could say is WOW. The sound suddenly became much fuller. The soundstage got even wider. Details also improved, while forming extremely accurate percussions. With some Sovtek B tubes installed (see LD2++ threads), the bass hits extended much lower. The most important of all, however, is the improvement in the mids department. Because the LD2++ is a very warm amp with liquid-like mids, it filled up the rather flat TC-7510. It totally changed the HD595 experience.

Last but not least was a generic gold-plated RCA connection to Meier Audio's Corda Headfive solid-state amplifier. Although the last method tested, I'm the most impressed with the result of its sound. I must be in heaven, because there is no other way to describe the sound of which I was hearing. Again, the soundstage was incredible, coupled with an amazing reproduction of the frequency scale. Great bass, fantastic mid-range, and non-piercing but crystal highs. Coupled with the Sennheiser HD595, not only did the percussions sounded accurate, but there was simply an extremely pleasant balance of upper and lower mid-range. The bass was neither overpowering nor underwhelming. Low notes hit fast and deep; in another word, clean. In all, although geared a bit towards the warm side, the entire frequency scale was very accurately portrayed.


Headphone Internal Amp/Jack (6 /10)

Comparing to conventional headphone jacks from CD players or laptops, the headphone jack provided a much fuller sound. Comparing to the sound coming from the LD2++, however, it appeared less refined. The biggest fault of this headphone jack is the extremely high noise floor. I could hear considerable hiss through both the HD595 and the HD580. The noise did not increase as the volume pot was turned up. In my opinion, the high hiss level has made this headphone jack unacceptable to me. Although you can't really hear the hiss during music playback, to me, it shows that the internal headphone amp design still needs further improvement, even if that is not the main purposed function of a DAC. If this part can be improved, I'm sure that the TC-7510 will become an extremely popular desktop DAC/headphone amp integrated combo.


Conclusion (8 /10) ***INITIAL***

In all, I'm extremely impressed with the initial impression, and i'm sure the TC-7510 will continue to open up after many more hours of burn in. Besides the high noise level in the headphone jack, the Beresford proved itself to be an extremely competent DAC. Its compact size, solid construction, and portability goes very well with anyone seeking a more mobile setup. What is more, with a very full, detailed, and accurate sound, it is able to handle pretty much whatever i throw at it. However, at some areas of several songs I listened to, I could notice a bit of congestion. Nonetheless, further burn-in is required to make the final judgement. Right now, all i can say is I will never listen to my amp without my new DAC again!

The MSRP of the MKIII is 99 Pounds.

Great review!!! I agree 100% with your finding.

Among all the DACs I owned, here is how I rank them (based on memory comparison):
1. CIAudio VDA-2 DAC / VAC-1 PSU
2. Musical Fidelity A3.24 DAC
3. Modded TCC TC-7510 24bit/96khz with SLA Battery
4. Modded Scott Nixon TubeDac+ with Custom Power Supply
5. Ack Dack 1.2e
6. Curcio Audio Engineering based Tube DAC
7. Modded Zhaolu D2 (Caps bypassed) with CS4398 Board
8. Modwright CIAudio VDA1 / VAC1
9. Headroom MicroDAC (again)
10. Modded ART DI/O
11. MisterX Alien DAC

I replaced the power cap. With this mod, it gives better bass extention and speed. I use it in my speaker system with SLA 12vDC with inline 3amp fuse.

Nice review thanks!!

Can you take pics of the inside? My understanding is those DACs use a single OP amp to drive the headphone. If that is the case, it might be a gain issue, so swapping gain resistors could work. The other option is to use an impedance adapter with the cans, although this may color the sound.

Most line outs are designed to push higher impedance loads, typically presented by amps and preamps. So your impressions plugging the cans in directly are not too surprising.

I will open the DAC tomorrow and take some pics of the inside. Right now, im still burning the thing in, so i don't wanna open it yet!
