Hi, I’m reading a Topping D90SE DAC Review at: https://soundnews.net/sources/dacs/topping-d90se-dac-review/. It seems the author rewards Matrix Element X as the best device: „comparing it with its predecessor and also with my own Matrix Audio Element X…which by the way, was never beaten at its...

Hi, are there any mature SSD based NAS solutions on the market? Can this become the mainstream in the future

Hi, generally speaking, a room shall have more diffusors than absorbers for a better acoustic quality. What about a tiny room smaller than 6m^2? Is absorbing more important because echoes are more serious?

Hi, does anyone have experience with Hxmelody HX600: https://www.thanksbuyer.com/hxmelody-hx600-silver-digital-streaming-player-digital-music-streamer-without-decoding-chip-85780. Is this comparable with Matrix Element S: https://www.matrix-digi.com/product/90/element_S?

Hi, On page 13 of this document http://www.audiophilleo.com/zh_hk/docs/Dunn-AP-tn23.pdf a term “jitter attenuation” can be found. Is it a technique on the DAC?

Hi, Does it make any difference on sound quality if the data is received by a streamer over Ethernet or local USB interface?

Hi, Can I assert asynchronous DACs are the ideal solution for streamer problems? It doesn’t matter if the shielding, the power linearity and the jitter of a streamer are good or not. The DAC reads the audio data and does a re-clocking with the perfect stability. If so I’d prefer a streamer with...

Hi, I’m interested in HoloAudio Red: https://magnahifi.com/holoaudio-red-network-streamer-ddc-i2s-dsd1024/ as a streamer. This streamer only takes audio data from the Ethernet port. Question 1: Do I need an Ethernet switch and a network hard drive if I prefer the local resources? Question 2...

Hi, has anyone tested Silent Angel M1T? I just wan to know which method gives better audio performance: local hard disk (SSD) or network transport (via switch)?

Hi, I want a standalone player to play music from an SSD. Do I need a Roon core such as Silent Angel Z1 in this case?

Hi, I want to use 60cm x 60cm full frequency range absorbers to cover a 3.6m (W) x 2.6m (H) wall. Shall the whole area be covered as much as possible or some uncovered area is allowed?

Hi, I want to decorate the ceiling of my small room for music listening with two bookshelf loudspeakers. How about this Mineral Ceiling Tile (https://www.knaufceilingsolutions.com/en/products/armstrong-fine-fissured-rh99/) with 8cm thick polyester fiber? Will I get the balance of low, mid and...

Hi, I have the following problem with my Arcam CD73 player. While playing some CDs with a sudden high signal level (for example playing piano with a full force) there is noise. I tried the same music with my PC. It’s OK even though my PC isn’t high end. I suspect the CD player DAC leads to this...

I just have a question related to the combination Digital Audio Player + DAC. Shall only one of both be MQA capable or must both be so? If only one MQA capable device is OK which one would you recommend, DAP or DAC?

Hi, can anyone recommend a commercial DAP based on Raspberry Pi with display and USB interface to DAC?

Hi, sometimes the audio decoder is integrated in the DAP but sometimes in the DAC. Should we take this into consideration when selecting the combination DAP + DAC so that the audio signal is not decoded twice? What would you suggest?

Hi, I notice all the DAP test reviews only focus on analog outputs such as waveforms, spectrums and so on. What about digital outputs such as optical and coaxial? Don’t they affect audio performance?

Hi, Most DAPs have an internal DAC. Why do many still buy external desktop DACs instead? For better audio qualtiy? Is it very difficult to integrate good quality DACs into DAPs?

Hi, how much is the quantative degradation (in SNR, THD, SINAD or something else?) if the audio source such as a CD player is connected with the hp amp through the SE or BAL mode? Maybe some reviews would be helpful.

Hi, I’m new to this field. I just used a mobile player to drive one open back hp (sensitivity = 103dB) and one closed back one (sensitivity = 98dB) in SE mode. I found out with the same volume configuration the open back hp creates a much weaker sound pressure level. Is this due to sensitivity...
