Line Magnetic quality

I have owned the 211ia and currently own the 518ia.  Superb amplifiers.  Give Charlie at Stereo Haven a call.....he will fix u up.

My first serious amp is LM 508ia. Been enjoying since last week on my pair of 10+ year old Paradigm Studio 40v3 pair of speakers. I got a demo version from a dealer and it sounds good to me. It is heavy and seems very well built it does perform better than my Marantz SR7005. Does put out a lot of heat just like any other class A amp I guess.

You should consider your speakers, how far you sit from them, how loud you like to listen to etc before going the tube way. But you may already know that.

I have a Primaluna.  It was made in China, and the build quality is excellent.  No reason the Line Magnetic can't also be an excellent piece!

The Cayin (aka Zhuhai Spark Electronic Equipment Co) brand gave birth to LM. Legend has it that the two brothers were engineers at Cayin, then struck out on their own. I've been told they source many parts from the same suppliers and have similar build quality. I have an early Cayin integrated, supposedly engineered by the LM brothers, that's now going on 12 years old. It operates as new and is built like a tank. Except for the bias boards, it's all hand-wired with a very tidy layout. It has only high quality parts: Takman, Nichicon, Clarity...and much quieter transformers than found in one of the major American competitors. Zero hum or buzz can be heard through my speakers at idle, only the slightest hiss with ears against the tweeters.

My DAC is an LM model and also built like a BSH - again, very high quality parts throughout, no corner cutting. 

I have a Triode TRV 845 stereo amp.   Triode equipment is made by LM to Triode design specifications.   While not a LM branded amp I can say that build quality is outstanding.   Reliability has been excellent.  Bias has held rock steady for 2yrs.     You will be happy with a LM amp.
