Hello! This is a quick review/measurements set of a Pioneer DV-565A CD/DVD player, tested in CD mode. The unit itself is built and feels like a typical Mid-Fi: generally pleasant appearance, but all buttons have almost no travel and sometimes require force to be activated. We have a decent...

Hello! This is a quick review/measurements set of a Pioneer DV-717 CD/DVD player, tested in CD mode. I was loaned this unit just for a few days, so I took an opportunity to measure such a high-end (for early 2000s) device. Well, at least it looks cool. Released in 1998 it had a price of...

This is a review and detailed measurements of the O-NOORUS D4 stereo integrated amplifier. It was sent to me by the company and costs US$139 from them direct with the 48V/5A power brick. It is fundamentally a small box TPA3255 design with PFFB to give a flat response into any load, but it has...

Hello everyone,in this video review: I got three Up2Cast amp boards from Arylic,with these boards I will try to set up tri-amping. The Up2Cast amp board is based on the ACM8628 chip and has a good output power (25w x2 8ohm 24v),despite its modest size. The board is interesting due to the...

I am debating whether to get the Topping E2x2 OTG or the E8x8-Pre. Is the $250 price difference on Amazon justified? (The E2xE OTG is $200, while the E8x8-Pre is $450.) I haven't found any reviews of the E8x8, which makes it hard for me to commit to it. However, the extra ADAT out, secondary...

Hello everyone,in this video: I got a four-channel amplifier from Wondom for review on two TDA7498E microcircuits and with a built-in adau1701 dsp module with a maximum sampling frequency of 48000khz 24bit. The amplifier has many options for connecting and transmitting a signal to it.The...

Hi, This is my second attempt at CD player measurements, based on the knowledge I gained from ASR. Many thanks to the members who contributed to developing this part of the reviews, especially @NTTY, who shared their measured files with me. Some of these files were used in this review. The...

Hi, This is a measurement of the phono preamp Behringer PP400. It is a simple preamp without any switches and costs around US$25-30. For measurements, I grounded the PP400 through its output to the analyser. Using a dedicated screw caused significant distortion from the power supply. Below...

I've been after a better bench supply for a while, as my usual one runs out of amps and/or volts when testing power amp modules. When I saw this 60V/20A supply on sale I thought I had to try it. We are talking US$130 shipped for 1200W of power. Too good to be true? Let's find out! I have a...

So I've had this player in the closet for many years. Did not get much use due to use of streaming and ripping my CD collection. But anyway, it contains dual Wolfson DACs WM8740 and with the use of @NTTY s recent work I ripped some test files to CD and made a few tests. This is not a...

Hi, this is a review of digital to analog converter which I bought on a local (Polish) e-commerce platform. Since it is a no-name company, I called it $5 DAC which also indicates its price. You can easily find similar DACs on Amazon or Aliexpress but the price can vary from $5 to $20. The...

The frequency response in this D9.2 review looks weird. It is also different from the frequency response in magazine reviews of the previous version D9. The high is much elevated. Frekvenční odezva - v ose (červená) a pod úhlem 30° (černá) (Bing translation: Frequency Response - Axis (Red)...

Hi everybody! I recently started a personal and relative (temporal) investment on searching a reasonable good audio setup specific to classical music playback. Initially was oriented towards audiophile pre-amp, amp and speakers and made a travel to Madrid (capital of Spain) to listen at...
