“The Momentum M400 employs the same chassis with a small aesthetic design change to the copper feature on the faceplate sides. Additionally, the meter now displays a scale appropriate for the greater output. With the Momentum M400, Dan has once again elevated the state of the art in amplifier design. ”

” Driving 20 output tubes per channel at high frequency needs a lot of current, and the 814 tube has a lot to spare. The driver tube is chple loaded, and is DC coupled to the output stage,for supreme slew rate numbers and transparency. The driver stage power supply I s fed by separate transformers and is double filtered using chokes.”

Magnusaudio AMP REVIEW

November 18, 2015 Comments Off on Magnusaudio AMP REVIEW

” Comparing the two class A champs netted two quite distinct flavours. The Magnus played what seemed like a virtual stand-in for the EJ Sarmento-rebooted James Bongiorno Son of Ampzilla II. I obviously couldn’t isolate whether this was down to shared versus dissimilar transistors types. Here the play pen was about BJT versus Mosfet. Did this difference merely reiterate their core signatures which anyone intimately familiar with either device would recognize? Regardless, the MA-260 focused down on the more compact, with sharper crisper edging and a cooler more bluish colour temp. The XA30.8 was the spatially more expansive and generous, its focus not locked down as hard, its outlines softer and the overall hue more honey and warm. Purely by outcome, I thought of the Magnus as endowed with more 3rd-order THD than the Pass. Shifting harmonic distribution from 2nd to 3rd-order preponderance usually nets exactly this offset. Whether here it was the actual cause is wholly academic. The task is to describe sonic flavours in terms experienced listeners can relate to. If you’ve more versed in basic tube types, the MA-260 played to pentode-run EL84 precedents like Trafomatic Audio’s Kaivalya monos, the XA30.8 more to 845 triode specimens.”

Schiit Ragnarok stereo amplifier Audiophiliac Component of the Year

” For my listening tests I first hooked up Ragnarok to my Magnepan .7 flat panel speakers, precisely because they are far and away the best speakers I’ve heard for the money, but they’re a brutal load for amplifiers, and most AV receivers and budget integrated amps never come close to making the .7 speakers sing. The Ragnarok fully exploited these speakers potential.”

Benchmark Media Systems AHB2 power amplifier review

November 14, 2015 Comments Off on Benchmark Media Systems AHB2 power amplifier review

” Tonal balance is a curious audio parameter. Careful listeners often hear what sounds like an uneven or tilted frequency balance, even when measurements taken under lab conditions show it to be flat. Lots of real-world factors might account for this, including interaction of an amplifier’s output stage with the complex input impedance of a loudspeaker. At first, I thought the AHB2 sounded less bright, and less full in the bass, than the other amps I had on hand, but after only a few days of listening I began to accept that it sounded more “right” than any of them. Now the treble wasn’t so much un-bright as smoother and unaccented. The bass had all requisite extension and detail (see above), but seemed to be more naturally balanced with the rest of the audio band.”

NuPrime Audio IDA-8 Integrated Amplifier-DAC Review

November 12, 2015 Comments Off on NuPrime Audio IDA-8 Integrated Amplifier-DAC Review

” The orchestral strings of the Trondheim Soloists, in Marianne Thorsen’s recordings of Mozart’s Violin Concertos Nos 4-5 (24/352.8 FLAC, 2L), were smooth without sounding dull, with a wonderful sense of envelopment of Thorsen’s violin by the orchestra, even as soloist and ensemble remained clearly distinct from each other. At very high volume levels, the IDA-8 could make the violins sound a bit hard. But at levels that to me are adequate — but that some might consider quite loud — the NuPrime remained wholly composed. The same was true of pop recordings such as Carly Rae Jepsen’s surprisingly well-produced E·mo·tion (24/44.1 FLAC, Universal), which the IDA-8 had no problem reproducing at high levels. Jepsen’s voice is quite closely miked and exhibits moderate sibilance, but the IDA-8 reproduced it with neutral, easygoing sound, while having enough power to drive both the GoldenEar Triton Fives and KEF R900s to volumes high enough that I could immensely enjoy the high-energy pop sensibility of her performance.”

Naim NAP 250 DR REVIEW

November 7, 2015 Comments Off on Naim NAP 250 DR REVIEW

” got to hear a public demonstration of the previous generation of NAP 250 compared with the DR version at an Audio T event in Brighton. It was a large room with a lot of people in it and I had a pretty poor seat but even so the increase in transparency and reduction in hash/noise was very clear. Most of the Naim amplifiers I have reviewed had a slightly earthy sound with limited perceived bandwidth, which is not unappealing but less revealing than the best of the alternatives. This did not stop their timing skills from being apparent and the success of the company has been built on that sound, so clearly it works. With DR Naim seems to have retained the pace, rhythm and timing and added power and transparency, so the NAP 250 DR now has low end grunt that makes for extremely muscular bass with the right speaker.’

Musical Fidelity Nu-Vista 800 integrated amplifier Review

November 2, 2015 Comments Off on Musical Fidelity Nu-Vista 800 integrated amplifier Review

Read Here

” After matching levels between my two different Nu-Vista 800 setups—with a line-level source driving its balanced inputs, and with the outputs of my darTZeel preamp driving its single-ended inputs—switching between them revealed, in the latter, a very slight diminution in bass definition (but not extension), and a barely perceptible softening of high-frequency transients (so slight as to probably not be noticeable to most listeners). While the latter would be beneficial to an overanalytical component that made transients too sharp and defined on top and overdamped on the bottom, they weren’t at all what the Nu-Vista 800 needed. Therefore, I did all of my listening to digital recordings through the Nu-Vista 800’s balanced input, with the DAC’s analog outputs directly feeding the amplifier”
