Entry-level Conrad-Johnson vs Line Magnetic

Snoober

Dysthymic
I owned components from both of these manufacturers so I just wanted to mention very briefly my impressions. This is a comparison between the Conrad-Johnson MV60SE / ET3SE combo vs the Line Magnetic 216IA. The MV60SE is very similar to the current Classic 60, with the probable exception being the Classic 60 possessing Teflon caps. Although CJ fans will refute this, the Teflon caps don't necessarily always make things better imo (re: ET3 vs ET3SE). I did my listening mostly with Revel Performa F52s.

Please read this with the caveat that are just my personal impressions using my equipment, so I hope I don't offend anybody with regard to his/her own equipment choices.

My main complaint about the CJ gear's sound is that not once did it convince me that I might be listening to a live performer in my room. I am told that this is mitigated by going up the CJ line, but how far up the financial ladder do I have to climb to get there? Ahem, really far, it seems. I think the CJ gear (in my system) had a lower midrange and upper bass leanness that contributed to the failure to substantially anchor voices in the recording. In contradistinction, the little 216IA startles me with its realism regularly. I rolled countless tube combinations but they did little to get things just where I wanted them in the CJ setup.

That said, the CJ combo has superior detail retrieval and excels at placing instruments precisely in space. The soundstage width is huge with CJ. The LM amp cannot match this. What the LM does better is its ability to render soundstage depth. I always thought the CJ system was a little 2-dimensional in its presentation.

For deep bass reproduction the CJ gear just kills the LM. Bass just thunders down to 20Hz and it can be terrifying listening to an orchestra at full tilt. By contrast, the LM has a plumper midbass and less low bass output overall. At just 38wpc I don't think the LM amp holds the musical presentation together too well when things get really loud. The KT120-equipped 60wpc CJ is unflappable.

Tone-wise, the LM is less mellow than the CJ gear though the highs are not too hot. Voices appear at the speaker baffles with LM compared to CJ's mid-hall perspective. I guess this contributes to making the sound more 'palpable' through LM. I always considered the CJ sound very 'cerebral'.

I did have a problem with the CJ lacking in rhythmic drive and pace. Here is where the LM pulled far out ahead. It may be due to the interaction between the Revel woofers and the CJ gear not being ideal. Anyway, if foot-tapping fun is your thing Line Magnetic will probably get you there.

As to build-quality: CJ trumps LM on the external chassis. And foibles? The cheapskate CJ remote compared to a billet of aluminum from LM. Also, the LM is dead silent at the speakers whereas I could hear the 'tube-rush' with the CJ gear. Oh, the CJ 'turn-off' thump at the speakers, I find, is just shameful for a $3500 amp. I have no quibbles with the LM gear.

Um, yeah, I hope this was helpful to anyone shopping at the shallow end of the pool. I will be selling my 216IA soon, however. Why? I want LM SET. :D

Snoober - I just noticed this post and felt like responding, even though the post is 4 months old. I have not heard Line Magnetic yet, although I very much want to. But my impressions of my CJ amp are so contrary to yours, I wanted share them. I'm not promoting CJ, just commenting. I have a Premier 11a, the predecessor to the MV60se. My Premier 11a has the teflon cap upgrade, mind you I bought it this way, so have not heard the non-teflon 11a to compare. I find my setup to be particularly fast, dynamic, clear (transparent) with gobs of energy. I agree the sound seems to come from further back, as opposed to being pushed forward. But that is actually a plus considering my near field listening situation.The rhythmic thrust is impressive (even moreso than my same setup with a Plinius integrated amp in the mix before (I'm even using a passive pre with the CJ!). I wonder if speaker/amp/source interaction has something to do with the extreme differences we seem to experience. I do notice much more energy when I'm using my TT or tuner as source - the cd player does seem a bit "slower". So, no definitive conclusion, just wanted to share a different experience, also perhaps different listener priorities. But I do understand your learyness about "one needing to go further up the model line, or upgrading to teflon caps to get to that better place". I am very curious as to what Line Magnetic has to offer. Would like to hear your impressions of the new amp.
 
I find this thread interesting and I hope more folks can contribute to it.

I am familiar with older CJ equipment and have a pre and amp in the pipeline to trade for a piece of mine and am curious about the LM equipment - so this is timely for me.
 
If you liked the Line Magnetic unit, you might also like the Rogue Audio Cronus Magnum, if you can get a chance to listen to one of them. They're a little more expensive new ($2400 as opposed to $1900), but they do seem to do very well in the sonic departments you mentioned... and it's more power (100w/ch) than either the CH or the LM. That, ostensibly, should help the dynamics...

Regards,
Gordon.
