  1. Dima Rodionov, слушаю различные стили. Фактически всё что Вы озвучили. Хотелось бы, чтобы наушники любой жанр отыгрывали минимум на четыре с плюсом, за такие деньги. Я предполагаю, что Fostex более сбалансированные, смогут отыграть как джаз и классику, так и инструментальные, динамичные партии, и конечно же рок-н-ролл. Sennheiser же, я слушал, всё нравится, кроме недостатка динамики и баса.
  2. Есть обзор, зарубежный, про Element X: You are seeing what I am seeing? First DAC ever to break the 120 dB SINAD (signal over noise and distortion mark)!!! Distortion in the good channel is down a whopping 130 dB! Notice the perfect channel match. See the generated frequency of 1 kHz right on the money. Needless to say, the Element X comfortably takes the crown of the best DAC I have tested. The unit has some headroom and if you max the output, you get another half a volt with SINAD "dropping" to 118 dB. Notice the FFT noise floor down the weeds, almost falling off the chart. We can see the effect of that in exceptional dynamic range. Spec is 130 dB but we can all forgive them for slightly lower performance. Likely they are subtracting the noise of the Audio Precision analyzer to get their number. Surely there is something broken here that we can find. How about linearity? Picture perfect! 20 bits of resolution without trying hard. We have to expect good performance in our 32-tone test given the great SINAD and indeed we get that. Intermodulation distortion is likewise excellent. It is beating Topping DX3 Pro which is a very hard thing to do. You can see that tiny raise in distortion at the limit which is why -1 dB gives slightly lower distortion still. How about jitter? Surely there is some noise there from display, the networking subsystem, etc. Once again noise floor is so low it is falling off the chart which normally would reveal anything problematic. But none is there. The few spikes on the left are at most -140 dB below our test signal at 12 kHz. We are talking 25 dB headroom over your hearing dynamic range. Someone scrubbed the heck out of every noise and crosstalk inside the Element X. THD+N versus frequency shows that the unit provides the same performance across the full audible range.At this point, we are stuck with the mundane measurements like frequency response. Ideally we see everything flat to 20 kHz and then fully attenuated by 22.05 kHz. Filters 5 and 7 give you that. The default filter 1 is not bad as it gives the flattest response but takes up to 24 kHz to provide full attenuation. Network Audio Performance: The Element X is "RoonReady" which I was very pleased to see although there is a warning in Roon saying it is not certified. Using Roon, I played my standard 1 khz tone and got the same result as using USB shown before. So we have bit perfect performance here just as well (sorry the FFT is not calibrated with respect to level).Headphone Amplifier Measurements. Let's start with dynamic range test at full level. So we have bit perfect performance here just as well (sorry the FFT is not calibrated with respect to level). Headphone Amplifier Measurements: Let's start with dynamic range test at full level. Can't ask for more. Here it is at just 50 millivolts though for sensitive headphones. Ah, that is not quite as excellent as the rest of the unit. Output impedance is spec'ed at 1.5 ohm and my measurements essentially show the same. Should not be a problem for just about every headphone. Most important measurement here is the amount of power versus distortion. First 300 Ohm. Other than low gain being a bit noisier than Topping DX3 Pro low gain, it cleans DX3 Pro's clock in output power. I usually like to see 100 milliwatts here and the Element X gets 280 milliwatts. That should give plenty of headroom to drive even higher impedance headphones. Notice that even low gain has a lot of power. Conversely, there is not much penalty to using high-gain. In that mode, around +2 dB on volume control, you hear a relay and another gain stage clicks in. In other words, it is a clever multi-gain setting where in low volume you don't pay much penalty for noise. Comparing to Massdrop THX AAA 789 in unbalanced mode, we get. We actually have almost twice as much power available! Signal to noise ratio though is a bit worse than THX. Switching to 33 ohm load to emphasize current delivery, we get. Once again, we have tons of power to the tune of 1.2 watts. Balanced Headphone Amplifier Measurements: Switching in my 50 ohm balanced load, we get this as compared to Massdrop THX AAA 789. We have more than 1.8 watts of power now. We do fall short of catching up to THX AAA 789 though on noise, distortion and max power. What is there though should be ample for just about any headphone there. Subjective Listening Tests: I connected to Sennheiser HD-650 headphones to the Element X and started listening to my critical playlist for headphone amplifiers. Ah, this was a sublime experience. I had infinite power and could easily have my ear lobes resonate with the music if I wanted. Resolution, fine detail, etc. was as good as you could get, limited just by the content itself. It was so good that I sat there going through my audiophile playlist, just enjoying the music. I then fired up Roon and told it to play the Tidal Jazz playlist. It was fun to see the MQA indicator light up on the DAC. I did a quick test of having Roon decode MQA versus the Element X and was surprised that the latter had a bit more highs and different tonality. It is a difficult test because you have a 5 second or so switchover time in Roon. I should capture the output both ways and compare. Conclusions: I was full of excitement when I finished the DAC testing last night. It is not everyday that a piece of audio equipment clears such important bencharms. No question about it: the Matrix Audio Element X is superbly engineered. According to the company they use an Audio Precision analyzer to verify their performance so no wonder no stone was left unturned as far as optimizing its performance. The headphone amplifier is also wonderful. It is certainly better than my everyday combo unit, the Topping DX3 Pro and by a mile as far as available power. The all-in-one functionality is great to have in this integrated fashion. Push your audio streams to it with your PC or phone anywhere. No need to build a media server and putting it next to the DAC. You get pride of ownership in the industrial design and fit and finish. The company principal is active on this forum and willing to have their gear measured which is a huge plus in my book. So it comes down to the US $3,000 price tag. Not everyone can afford this of course. But provides aspiration to save up and purchase it. For those who can purchase it now, you can buy it and be done with your digital to analog pipeline. You will have the comfort of knowing that you have a state-of-the-art DAC, streamer and headphone amplifier that puts countless high-end products to shame. I am going to give my highest recommendation for Matrix Audio Element X. Congratulations and thanks for putting engineering and quality first.
  3. Здравствуйте дорогие форумчане! Хотел бы задать вопрос, который меня долго мучает. Хочу приобрести наушники для своего Denon-DA-300 USB (ЦАП) и Musical Fidelity X-CAN v3 (Усилитель). Вот не могу никак понять, раскроет ли эта пара Sennheiser, Fostex? На Sennheiser у меня вообще почти нет веры, так-как там аж 300 Ом. Если ли на них надежда? У Fostex-ов же 25 Ом. Тем более Denon 9200 имеют схожую компоновку (драйверы, Ом). Я имею сейчас наушники V-MODA CROSSFADE M-100 (32 Ом). Играют отлично за свою цену, но их неудобство амбушюр (форма), меня крайне напрягает, через час, уши ужасно болят. Форма ромбическая, очень странная. Их звук басовитый, очень динамичный и драйвовый. Я предполагаю, что они будут чем-то стилистически похожи на Fostex TH909. Sennheiser же открытые полностью, меньше баса. Я их слушал, на HDVD 800, очень понравились. Сцена и масштаб цепляет, но не хватает баса. Но я готов с этим смериться, так-как 800-ки уж слишком удобные и лёгкие. Если вообще совсем всё плохо с моей парой ЦАП+Усилитель, то я готов приобрести Matrix Element X. Уж он то, я надеюсь, раскачает как надо Sennheiser, Fostex? На них стоит последний ES9038. Подойдёт ли он для Fostex? Говорят Sabre довольно жёсткий, как раз для воздушных Sennheiser, а для Fostex нужен более мягкий AK4497? И ещё, хотелось бы подробное описание звучания Fostex TH909. Я вообще ни разу не слушал Fostex. У меня нет возможности, в моем городе не послушать. Буду очень благодарен за помощь.
