來自美國的Rogue Audio以務實的價格求得好聲為最大目標,因此雖然器材都是Made in USA,但是價位都是相當平易近人,不會高不可攀,聲音表現也早已得到肯定,本次試聽的是Metis前級與Medusa後級的組合。Rogue Audio的老鷹標記,香港就稱這品牌為"雀仔"。 Rogue Audio "Metis" 前級 Rogue Audio "Medusa" 後級 請接下一頁↓ Rogue Audio Metis Magnum 前級內部公開 這台Metis前級也是Magnum的版本,包括更大的電源供應與模組,更大的耦合電容, Cardas配線、更好的電容、電阻、鍍金真空管座...等等 - Larger power supply - Power supply mods - Larger coupling capacitors - Cardas output wiring - Polypropylene byass capacitors - Precision Dale-Vishay resistors in critical spots - HexFred diodes - Gold tube sockets - Magnum logo on faceplate 若是有對照原廠官網非Magnum版本的內部圖,就會發現Magnum好很多 使用兩隻6SN7真空管,原廠外盒有標示那隻要插在前面 還有真空管的保護金屬罩,蠻實用的 前級的遙控器,用來控制音量 Metis有12dB的增益放大,內建的MM唱放為38dB,前方有動差式的耳擴輸出 介面方面,有4組RCA輸入(line 1,2,3與MM唱放),1組固定的輸出(不受音量控制)、1組受音量控制的輸出 完全在美國設計與生產 General Features and Specifications: - 20Hz-30KHz bandwidth - Slow start turn on sequencing - 12 dB gain line stage - Ultra accurate 38dB gain phono - Discrete headphone amplifiery - Massive high storage linear power supply - (2) 6SN7 tubes - Gold plated RCA inputs - Machined aluminum faceplate - 4 inputs (phono, line 1,2,3) - 1 pair fixed outputs - 1 pair variable outputs - All precision components - Heavy (2 ounce) copper circuit board - Fully tested, burned-in, and auditioned - Detachable IEC power cord - 18" W x 12.5"D X 4.5" H, 16 LB (22LB shipping weight) - power requirements: 120V or 230V - 50/60Hz - Entirely designed and hand built in the USA 請接下一頁↓ Rogue Audio Medusa 後級內部公開 Medusa是D類晶體與真空管混合的後級,有著真空管豐富的音樂性及晶體的動態。Medusa的設計不是單純的直接在D類放大前加上真空管線路,使用的是Rogue Audio獨家的tubeD™線路架構,實際將兩者結合在一起。待機時晶體放大部份仍有提供電力,真空管則是較緩慢的啟用,以保護真空管。Medusa輸出功率為200W(8 Ohms), 400W (4 Ohms)。 打開內部就可看到兩顆一大一小的環型變壓器 這兩片應該是客訂的荷蘭Hypex D類晶體放大的模組,左、右聲道各一組 真空管放大部份,採用兩隻ECC802 S,與12AU7可替換 具有RCA與XLR輸入各一組 General Features: - Large high performance torodal transformers - Massive linear power supplies - Balanced (XLR) and single ended (RCA) inputs - Heavy-duty gold plated binding posts - Two 12AU7 tube complement - Short circuit protection - Standby circuitry for solid state components - Slow start circuit for extended tube life - Machined aluminum faceplate - Heavy (2 ounce) copper circuit board - All precision components - Fully tested, burned in, and auditioned Specifications: - Output power Medusa: 200/400 WPC 8/4 Ohms - Input impedance: 200K Ohms - frequency response: 10Hz - 20KHz ± 1dB - THD: <0.1% typ., <1.0% at rated power - input sensitivity: 1.0V RMS - dimensions: 18" W x 15" D x 5.5" H - weight: Medusa 38 lbs - power requirements: 115/230V - 50/60Hz
