This is a review and detailed measurements of the Mofi Studiophono MM/MC phono preamplifier. It is on kind loan from a member and costs US $349. The packaging has a retro feel to it and I don't mean that as a positive. When a device has the word "studio" in it, I expect solid metal enclosure...

As most of you probably know, I reviewed the Tekton M-Lore speaker back in October of last year. Company recently complained that my measurements were in error due to woofer being listening axis and not the tweeter (speaker manual disputes this). And that without the feet, the holes that house...

This is a review and detailed measurements of the Topping D50 III balanced stereo DAC with support for parametric equalization. It was sent to me by the company and costs US $229. Sorry for the quality of the picture/display. It is quite dim compared to my photography light and when I tried to...

Man, it has been an intense week dealing with the Tekton situation. Someone made a great suggestion that I should do a review of something good. Powered up the Audio Precision and the software says the license is expired!!! No way to upgrade it until next work week. So I thought the heck...

As many of you I am sure have followed, both Erin and I were hit with legal threats from a company post our reviews. Given the unfairness of the situation, many of you came to our defenses and provided incredible level of support both financially and in many other ways such as legal and...

The Pacific Northwest Section of the Audio Engineering Society has presented meetings with jj that I and many of us really like and appreciate. The Chair of that group, Dan Mortensen, is trying to be nominated to be President of the parent AES organization, and needs 100 nominations from full...

This is a review, listening tests, EQ, and detailed measurements of the Revel F206 Floor-standing speaker. It is on kind loan from a member (new) and costs US $1347.50 each. Please excuse the mobile phone picture quality and plastics that are still on the speaker. I try to keep products as...

I don't know how many of you have been reading the Tekton review thread. But it seems that the company designer/owner has threatened Erin, forcing him to take down his video and written review of one of his speakers. As we all know, Erin's core contributions are measurements of the speaker and...

This is a review, listening tests, equalization and detailed measurements of the Hifiman Ananda Nano headphone. It was kindly purchased by a member for testing and costs US $499. The Nano looks attractive although the feel is not that of luxury. It is a bit light. The forward part of the pad...

This is a review and detailed measurements of the Fosi Audio V3 Mono class D amplifier. It was sent to me by the company. The price with the power supply I tested is US $139.99. I must say the concept of a "monoblock" amplifier in such a small size runs foul of any expectation a longtime...

This is a review, listening tests, EQ and detailed measurements of the Ascend Acoustics Sierra-1 V2 bookshelf speaker. It is on kind loan from a member and costs US $998 for a pair ($948 on sale). The finish is nice enough. The cabinet feels quite heavy for its size and especially in the front...

This is a review and detailed measurements of the Down4Sound JP95 4/1 channel car audio amplifier. It is on kind loan from a member and is on sale for $250. This is a massive amplifier with incredibly beefy terminals and many features. I am shocked that it sells for just $250. I configured...

This is a review and detailed measurements of the Akitika stereo amplifier kit. It was purchased preassembled by a member and kindly sent to me. As you see, the case is rather simple but for a kit, it is not bad. That large power switch is reassuring, giving you the feeling that it could...

This is a review and detailed measurements of the JBL Conceal C83 "invisible" speaker. It is on kind loan from a member and costs US $1,100. As the name indicates, this is basically a flat surface that you cut out in the wall and "tape and mud" the edges. Once painted, it can be made to look...

This is a review, listening tests, and detailed measurements of Fosi Audio SK02 USB powered DAC and balanced headphone amplifier. It was sent to me by the company and costs US $99.99 (€99.00). The SK02 is excellently designed. Having it horizontal gives comfortable access to the rotary volume...
