That is light weight, would be nicer if over 60kg.  This is not an average AV amp.  It is uber.  H ...

小弟好奇為何師兄說重量超過60KG會更好，會對其聲音有影響嗎? 還是其他方面?? 還請師兄賜教咯~

Heat is an issue.  Anything that made from metal will reduce heat.  Example is transformers, heat sinks and chassis all weight a lot.  It helps to dissipate heat and therefore, adds durability of the unit.  Heavy units always better lol... It doesn't make sound better directly, but prevent sound quality to get worst due to hi temp. Heavy transformers don't make sound better..well, in a way, helps indirectly...  Unlike tubes, heat is #1 enemy of solid state devices.  After all these years contributing funds to the hi end world.. .  Hi Fi veterans, even without electronics background should have hi end basic ideas.   I smile thinking of this amp driving Scala Utopia or Alexia speakers...hehe.., plus an active sub...

原來如此，就是簡單的散熱問題，看來小弟想的太複雜了，多謝師兄解惑~

auraheart

散熱 is not 簡單 for an amp like this even with forced air cooling...This is a low voltage amp because of heat.  I bet ya good part on R&D funds of this amp was spend on that.  Other difficulties could be how to mount the transformer safely on a card..how to avoid interference, how to fit everything on a card (need custom parts, like thin transformers, short caps, etc).  These are big issues and many more.  This is seven high power mono amps in a chassis with limited space.  One reason why I said this is light weight consider there are 7 power transformers inside...it is not one transformer for all channels as typical AV machines. This is not an everyday product and the best Av amp I've seen on this forum so far.  There are reasons for this to cost a lot, truly started from the ground up.   Unlike some so call hi end product..A basic low power, easy to design (with tons of after market reference, low R&D cost) 35 watt amp cost $12, 000 USD because it is hi end....

Why readers think it is heavy?...Seems I am the only one think it is light weight.... 50Kg is nothing...should be over 60.

足稱功放都還好，喇叭先慘，一日未擺好個位，搬都搬屎你題外話，還記得個陣一條友將部SONY大羅友由廳搬入房，到掉個陣由架搬落地幾痛苦，部廢紫成92Kgs，真係腰都斷

This amp doesn't build like a typical AV amp.  It is like a Hi Fi amp...well, harder to design and build than an average hi end amp because of very limited space/hi heat....Quite impressive .  Sound quality should be good but not likely as good as an average hi end amp because it works under low voltage (less heat).  This AV amp deserves a lot of credit for packing so much in a box.  Mr. 7up deserves a lot of credit too for this thread.  Something that is extraordinary and most of us have never seen regardless of it's price.  This is more unique than the Rogue Audio Magnum, which I like a lot.

兩鷄港幣? haha...more less 兩鷄 USD..lol....  Hi R&D cost, you know...plus custom parts.  I don't know this manufacture so I don't know how much their name worth.  Over 1鷄 USD is reasonable MRSP.
