| [#31] 想問下高手呢部機用料靚嗎? 好多外國大 power amplifier 會用 standby switch 抽起 driver 供電做 24/7 長開讓 power output to speaker 無障礙,不過呢啲 amp 喺 standby mode 都 draws 幾拾 watt 部機仍 "暖"。 |

| [#30] 想問下高手呢部機用料靚嗎? 嗰吓卜一聲係 DC 直流沖擊喇叭音圈產生,揭起喇叭網會見到個音盆彈出或者縮入,DC 入音圈,始終有害無益,可免則免。 起因開機通電瞬間電路正負上下臂不平衡,唔係同時達到工作電流,以至輸出中點非0v, 電路設計得好,上下臂各管配對接近,呢個開機瞬間不穩定電壓會好低,甚至唔會察覺,跟本唔須要有 relay 做延遲保護。 唔要 relay 做延遲保護。真正全平衡放大好易做到呢點,又或者單一對功率管放大都易搞,管愈多,愈難配對, |

| [#29] 想問下高手呢部機用料靚嗎? 我對喇叭用咗廿年, 比以前部後級既開機pop sound沖擊咗十年以上, 果下聲照理無乜殺傷力. |

| [#28] 想問下高手呢部機用料靚嗎? https://www.accuphase.com/technical_information/e-280_technical_information.pdf Relay 個 contact resistance 會越用越大好多名牌唔用喇,Accuphase 用 Mos-Fet 代替 relay 不過制造咗另一問題,Krell 有個 standby 制,長開喺 standby mode 暖住部機。 E-280 applies a MOS-FET switch instead of mechanical relay for speaker protection. Damping-Factor, reliability and sound quality are all improved by this MOS-FET switch. They have very low on-resistance of 1.9mΩ and high current capability of 130A. 下圖部機冇開幾年,電源都冇插所以 standby 燈冇着 ![]() 最後修改時間: 2023-12-29 10:24:16 |

| [#24] 想問下高手呢部機用料靚嗎? 其實output冇落relay 會好聲啲, 我以前部Adcom 都係咁. Naim係好野嚟, 不過d model唔易分? 前後級之間好似一定要用Din插駁? 最後修改時間: 2023-12-29 07:15:02 |

| [#23] 想問下高手呢部機用料靚嗎? 我唔會買 supernair 3 入門其實二手 202/200 前後級係好抵玩,呢個 budget 其實玩到 282/250 了 Naim 有 serial number 可以睇出廠年份,啲機十年如一日咁滯,202 282 已經出咗 N 咁多年了。 |
