有，佢個老大P series就係哩。
P5
以P5來講，使用两條PC，除低壓On/Of Circuit外，貨柜式設計，每聲道由牛至沉熱器，完全獨立，跟Bryston 6B, 4B, 9B等看齊，在港售價和Bryston, McIntosh做法不同，實際街價與加拿大本土售價相約，6皮多左右，和Bryston6B差不多，但6B只有3 ch。
再留意輸出，one channel driven和ALL channel driven(日糸Receiver最喜歡用one channel driven @1KHz最輕鬆負載下來報數)輸出都一樣 325w/500w @8/4 ohms，淨重130 lbs。
A5
看看A5，5聲道共用兩隻牛，one speaker loaded和ALL SPK LOADED，輸出就有分別，而且重量大減一半，意味用料減半。
又看看MCA 50(MCA 5改良版)，設計路向和A5 一樣，輸出一樣，但價錢較好。
PVA 5
Anthem還有班小兄弟，PVA series，由2聲道至8聲道，不過別超都唔多提。
本人年前upgrade HK Home Theatre，要物識一台/多台 7 ch. Power amp，search過Lexicon, Anthem, Parasound Halo series, Krell, Bryston, McIntosh等等，以每watt的單價來看(鬼佬雜誌口頭禪)，Anthem Power Amp仍在原產地生產(MRX除外)，在港仍有加價空間。{:1_245:}

50% LARGER POWER SUPPLY RESERVOIRS
More Power! More space to store it! With 225 watts, large banks of capacitors are needed to store all of the energy required for the immense dynamic bursts of various special effects in a movie, or the taxing crescendo of a solo piano. These amplifiers are the most powerful MCA amplifiers yet, employing 16,400 micro farads (μF) of capacitance per channel (that’s over 80,000 μF for the MCA 50). With so many joules of energy in reserve, when called upon, the MCA 20, MCA 30 and MCA 50 are able to deliver full bursts of power instantly and effortlessly.

2台都用相同水塘，Anthem玩嘢{:1_343:} 。Anyway, MCA 50重過A5，61lbs vs 57 lbs，個人覺得，配加拿大AV Multi Power Amp，一就P2+P5，唔糸就MCA20+MCA30/50，最堅就緊係老牌Bryston 6B+8B(4+4)sst square哩。
Anthony兄，新成員到, congratulatios！現在是轉營時機，改投資FF DSLR相機+24/85mm f/1.4之類正鏡，影啲正相和Movie clip，再用現有gears播放，我提過Oppo93放相超正，用投投+screen放相，sharpness當然不及TV，但趣味性高很多。
這樣，一來水可繼續吹，二來AV gears又可保，雙贏局面{:1_264:}

多謝 Big_McIn兄
F1.4太貴，家下開支多咗好多，唔可以好似之前咁買玩具了。
不過老婆都想將部450D換做60D同買支35.8同85.8玩下。
呢排晚晚望住套機真係好唔捨得，希望保得住啦{:1_256:}
有冇ching知MCA 50賣幾銀?

小弟用緊部Denon 3808, 唔知邊部MRX才可全面勝過我部機呢?

兩部風格好唔同.....不過空間感同環統細節就MRX比天龍好，天龍會比較直接同刺激，其實好睇你要Ｄ咩？
