Has anybody bought or heard a Chinese knock off amplifier?
Why buy a knock off top brand piece of gear if you can buy excellent gear from chinese brands with "incredible" perfomance price ratio?There are many very good chinese audio brands like Audio-GD, Line Magnetic, Cayin, etc. All of my audio gear, bu... 
Do I need bi amping?
Thank you. Very good info.I guess I will try it because I have the class D amp at hand and my speakers accept biamping. Just for fun, but I don't have high hopes. Valves are valves!

Thank you. Clear as water 
Do I need bi amping?
Maybe a dumb question, but I’m not an expert on the field.If I connect one amp to the high frequencies binding posts and one to the low frequencies binding posts of the speakers, and both amps are "feeding" a full range signal, I believe it won’t ... 
Do I need bi amping?
And yes, you are right, no one "needs" biamping, I meant, should I try it?I wrote a wrong tittle for the post 
Do I need bi amping?
Ok. I will try to see the result.But how an external active crossover will be revelatory if the internal speakers crossover is a limitation? I mean, if I only have one (1) pair of speakers, how do I biamp them using a different crossover point tha... 
Do I need bi amping?
Ok. I think I will try it that way.The only caveat is that the Concept 500 have the crossover at 2.5 khz so I will have the Class D amp runing a good part of the mid frequencies, maybe loosing some good 300B midrange smoothness. We’ll see.I think ... 
Do I need bi amping?
Well yes, both amps will get full bandwidth from the preamp, but, as they will be connected to different binding posts (high and low frequencies of the speakers), wouldnt the speakers demand from them only those frequencies?I mean, if the valve am... 
Do I need bi amping?
Well @lloydc using a crossover will make more complex the issue.With the passive XLR preamp I can level the XLR and RCA outputs and use the speaker's built in crossover. Less expense and easier set up. 
Do I need bi amping?
Yes, but maybe it's easier to use level the gain (on the XLR) with a passive preamp like this one:https://www.ebay.com/itm/253180664213It's cheaper more adecuate as it has XLR ins and outs like I need 
Do I need bi amping?
My Audio-gd Master 1 has two outputs, one XLR and one RCA. If it can drive both amps without problem, as I believe, I will use a cheap passive preamp on the XLR side to lower the XLR output level (it's higher than the RCA on the Master 1) to the C...

Well, let me gather some patience and strengh!  :-) 
Do I need bi amping?
Thank you GeorgeThat's a very good option to try. Thank you.Have you tried some similar configuration or do you know someone who did it? Is it really a good upgrade un sound? 
Do I need bi amping?
Thanks for answering.My speakers are the Q Acustics Concept 500 and eventhough they are not super efficient (90 dB), the 2x48 wpc of the LM-508 drive them very well. It has dinamics, tone, layering, bass, sweetness, everything. But as always, I gu... 
What sends shivers down your spine when you play it on your system?
+1 for Telegraph Road of Dire Straits (live). The guitar solo on this song (at about 4 min of the song) moves me like almost nothing else. It's a piece of art. Pure adrenaline.Also the final guitar solo on Tunnel of love from them too. Incredible!
