Headphone amplifier Ortofon HD-Q7
Miniature Ortofon HD-Q7 is not only the freshest (sales in Japan began in the last year), but also the most original phone amplifier in our review. It has a stylish and even some kind of DJ and unusually arranged - almost the entire area of the top panel holds a large volume control. Its designed as a universal headphone amplifier all types, and at the same time - and as a booster for phone outputs players. On the front panel next to the main output jack there is another - a 3.5mm "jack" just to connect these devices. On the rear panel there are the traditional line inputs RCA, as well as the simplest input selector, made in the form of a miniature toggle switch. The second switch is responsible for supplying power, HD-Q7 which receives from the usual 16 volt adapter. Assume that the amplifier is built on advanced high-speed operational amplifiers. This is indicated by baggy playable range with very low noise level.
Listening with headphones . With low sensitivity Audez'e amplifier had a difficult life. It has a fairly modest power output and in addition slightly squander lowercase. Therefore, almost no stock dynamics, and volume output falls almost to the maximum. However, note that even at the limits of the sound HD-Q7 does not arise any distortion or noticeable painting. Energy in the middle and high registers does not fade, as often happens with frail amplifiers.
Listening with headphones Denon AH-A100 Anniversary Edition. But this pair recommend you consider necessary. Two Japanese products so well complement each other by sound ideology that the system does not want to change anything. Aligned with the musical balance, some excess amount of bass and higher frequencies, which is found in jubilee phones Denon, here transformed into quality (and it is never superfluous). And the dynamics increases so that breathtaking. It seems that in our review, there is another perfect combination.
Listening with headphones Sennheiser HD 800. With high-impedance phones have HD-Q7 also have problems, though their scale is not as dramatic as with low sensitivity headphones. Here in the order and space, and tonal balance. Claims relate only absolute dynamics. Sound worked with microfracture apothecary accuracy, but on the explosive tutti pair Ortofon + Sennheiser lacking.
