在6Moons Audio 的一篇文章中, Frederic Beudot對F-117, Nagra BPS和Esoteric E03有很詳盡的評述, 若懂英文的話, 大家可以不妨仔細的看看.

原文
The striking characteristics of the Nighthawk's sound are its superb linearity, good extension and control and complete absence of harshness. If the Nagra BPS leans towards tonal intensity with good resolution and superb spatialization; the Esoteric E03 toward extreme transparency with phenomenal reach at both ends of the spectrum; the F117 sits squarely in the middle very much like the Audia Flight Phono but with slightly reduced dynamics.
The F117 does not have the Nagra’s tonal hues, is slightly less colorful but also faster and far more linear in the bass by avoiding the upper bass hump of the Swiss. The Nagra and its MC step-up transformers offer greater fluidity and soundstage spaciousness with richer tonal hues at the expense of added weight. The Nighthawk gives up some of the lushness and wetness to add zippiness, sharper transients and much better top-to-bottom linearity. Obviously the F117 does not come close to the Esoteric E03 for minute detail retrieval, abysmal depth or incredible front-to-back layering (nothing I’ve heard does) but more often than not was I surprised that the F117 could image just as broadly as the Japanese machine while its treble, though not as extended, felt just as clean and undistorted. Don't let this short introduction leave you with the impression of a cold or hard-sounding machine. The F117 is sweet and just on the warm side of neutral. The Nagra is simply more fluid and tonally intense, with its saturation dial turned even farther.
The Nighthawk’s only relative weakness vis-à-vis far pricier phono stages I listened to recently is a level of compression of micro dynamics. After experimenting with loading (and going from 100 to 500 ohms for the DL103) and fine-tuning arm and cartridge settings, I was able to really minimize this effect albeit not completely banish it. The F117 is very transparent to fine adjustment, just like other top phono stages I have reviewed this past year. It will let you know if something is wrong with your setup or record. If you feel cheated during a listening session—and unless you were comparing the F117 to the crème de la crème—any issue is more likely to stem from your setup than the Nighthawk.
譯文
夜鷹(Nighthawk)聲音的顯著特色是其高超的線性，良好的伸展和控制，完全沒有剌耳。如果Nagra BPS是傾向於音調的強度, 良好的分折力和卓越的空間感; 而Esoteric E03的走向則是極端的透明度，驚人兩端頻譜的伸展， F117剛在两者中間, 很像Audia Flight唱放但稍微不及它的動態。
F117沒有Nagra 的音調色彩，不及它的豐富多彩，但擁有更快、更線性的低音，避免了瑞士所產的(Nagra)在中低音域的谷峯。Nagra及其升壓牛則提供較好的流暢性和音場空間, 更豐富的色調, 但犧牲了質感。夜鷹則放棄一些豐滿和潤澤度, 卻增添了充沛的活力，更強烈的瞬態和更好的從高端到低端的線性。很明顯的F117不能在細節的還原力, 深不可測的深度或令人難以置信的前後端層次（沒有其它我聽過的能企及）可以接近Esoteric E03，但令人驚奇的是F117可以一樣有著日本機器(Esoteric E03)廣濶的音場, 而其高音，雖然在伸展度度不及，感覺就如同一般的清澈和沒有失真。不要讓這個簡短的介紹給你的印象F117是一部冷和硬的機器。F117是甜中帶中性的暖。簡單的說Nagra是比較流暢和色澤豐富，在飽和度方面更甚。
夜鷹的弱點只是在極微細的動態中有某程度上的壓縮, 是與我最近聽到的那些高價唱放有關。嘗試了不同的負載（由100至500歐姆;唱頭是DL103）和微調唱臂和唱頭設定後，我巳能夠真正減少在這方面的影響, 雖然還沒有完全消除。F117在微調上非常顯著，就像其它我過去一年評論中的頂級唱放一樣,。它會讓你知道如果是設置(組合)或唱片出問題。如果你在聆聽中有被騙的感覺的話，除非是你用來比較F117的是極品中的極品，任何問題的起因不是夜鷹而是你的組合。
