Line Magnetic 219ia vs Mc225


I am currently changing things up my system. I am looking to purchase a tube amp and have narrowed down quite a bit. I am unsure however, whether it would be more wise to go with a SET design or a push-pull design. The two amps in particular that I have in mind are either a Line Magnetic 210ia or 219ia SET 845/300B amplifier, or a vintage mc225 push pull amp with 7591 tubes of course. I waved the idea of a primaluna around but am pretty set on the two amps I’ve mentioned.. More will be familiar with the mc225 than will be with the line magnetic, but they get stupendous reviews and feedback, placing them as some of the best out there, next to shindo etc., in the tube amp world. The 225 obviously has its cult following as well, and is renowned and said by many to be maybe the best Mac amp of all time. (doesn’t matter)... anyway..

I am predominantly a record listener, but also listen to some digital and CD. My source pieces consist of a VPI Classic 2 turntable with a Soundsmith Zephyr 2 cartridge, an OPPO 105, and a Marantz 7701 preamp/ phono stage.

I have sold my previous speakers, and will be picking up a pair of 60’s vertical cornwalls this week. 102db obviously means that i do not have to consider wattage as a factor at all. I listen at low to moderate levels generally. Even 2 watts will have the cornwalls blaring. At this point the consideration is quality of wattage and current. The current will be responsible on the power to drive the 15" bass drivers in the cornwalls way more so than the wattage. The line magnetic SET amps will have no issues driving my speakers as they have large quality made transformers and move tons of current.

Here is the thing. I listen to jazz, classical cello and bass arco works, etc etc. I like soft rock as well. I also listen to very aggressive forms of rock. Hardcore, metal, thrash/speed metal, power violence, sludge, crust punk, etc etc. Those familiar, know what i mean. I am unsure on whether to go with a SET amp or PUSH PULL. Will one suit me better, or does it not necessarily matter, and either should do just fine? I know that the mc225 is known for being tubey, however natural, tight low end etc. The 219ia is known for being extremely transparent, refined, with a bold tight low end, beautiful 300B midrange, etc. Read Steve Huff’s review of this amp if you are unfamiliar. He calls it just about the best amp he has ever heard..... However will it does for the heavier stuff i listen to? This music is listened to on LP form more than less, and is recorded well and many are analog recordings.

Any input by those familiar with these two amps OR with push pull/SET amp comparisons in their own setups, please chime it with advice. I do appreciate it!

219ia has arrived....

And it sounds..........Absolutely wonderful. The allure of this amp glowing in my listening space alone is mesmerizing. What a cool looking amp. The dynamics that I stated as somewhat lacking in my current setup with the 500watt SS monos, are vastly improved. Drums have totally come alive. Voices have become more natural, and exceptionally SMOOTH. The bass still thick and driving well. The midrange FAR more cutting, present, clear, and clean, while staying smooth. The brightness of the horn tweeters is showing itself now, but it is a nice brightness, because it is smooth and pleasant. Everything just sounds more natural. I have listened for roughly an hour so far, all records. I will get around to more listening later this evening. The slight blanket over the speakers has been lifted. The sound is more inviting, open, and dynamic. Voices are FAR more into focus than they were. This thing makes my emotivas sound poor...

Hum that I was getting before is gone. The signal is dead quiet now, not even the faintest bit of hum. It was obviously the noisy circuits of the emotivas from what I can conclude.

I am still running through my marantz 7701 phono amp. The phono I am most interested in going with is the bottlehead Eros. All tube with a gain of 50db.

Very happy thus far....



Congratulations jkull. It's a great integrated. It has a big 3D sound stage as well. Enjoy!
Hello jkull,
It’s gratifying to read how pleased you are with the sound of your system with the addition of the LM 219ia SET amplifier. I’m not at all surprised and was pretty confident that it would turn out well for you. Your listening impressions are very early and quite enthusiastic, the good news is that the sound quality will further improve noticeably as the new amplifier burns in.

What you described is what high quality SETs are capable of providing with an appropriately matched speaker. Natural and realistic music reproduction that breathes life and emotion that is in some capacity unique to SET amplification. I can appreciate the stark contrast you distinguish between the SET and the SS emotiva, very different indeed. There is a genuine purity of the sound that enables an undeniable organic flesh and blood awareness to the listening experience. It makes some other amplifiers sound flat, uninspiring and frankly lifeless by comparison. As you've noticed already,  tone and harmonics are just more believable and resolved. 

You’ve received much feedback and opinions on this thread leading up to your decision to purchase the 219ia. I’m glad you took the opportunity to try this type of amplifier. In my opinion your admiration and sheer listening enjoyment are only going to increase over the course of time.

Thank you. I am very pleased, and relieved that I am this happy with the sound. I listened more last evening. The new ’Black Breath’ album was included.. For any listeners who enjoy heavy music, trust me, give this album a listen. It is dark, heavy, recorded beautifully, and is their best release yet. Sounded excellent at LOW volumes. Jeez I forgot, the best reward of all, and I need not exaggerate, the amp still sounds dynamic and involving at very low listening volumes. If you read above, that was one of the main goals I switched everything up, in order to achieve. Did some more gentle listening to a few contemporary jazz pieces as well. Sounds great. The horns REALLY sound amazing.

I am excited that there is even more potential to be unveiled, not that I honestly feel any ’needs improvement’ areas. Burn in of tubes, and an upgrade in my phono should inevitably do this however. I may even roll the 12AX7’s sooner than later. NOS mullards or something perhaps.. I wouldn’t waste my time doing it, unless if I bought tubes that would REALLY be worth my time.

Just a side note, I decided to try running my SVS in sealed mode last night as well. Never have since ownership. Plugged the three ports, and set the tuning mode to sealed. I was listening at very low volumes, with my wife in bed down the hall, but I could hear the tightening of the bass at this volume, so I look forward to trying it at louder volume today, to see what I think. I have the cornwalls handling the majority of the bass, and I think theyre doing a wonderful job of this, so the sub is basically in the mix for just the very low registers of bass, and extra oomph with the kick pedal, or extra body added to the upright bass etc etc. Ill probably mess around with this a bit furthermore.

Side note.. It is funny. After doing a hands on swap in my own home, with my own equipment, swapping just ONE component, and hearing SUCH a huge difference in sound quality on every level, I have to laugh at some of the philosophies I have read recently. In particular, some of the nonsense spewed by Harbeth’s Alan Shaw regarding how no amps should be showing sonic differences from another. Im not quoting him no, so don’t hold be accountable, but to summarize his statements, what I’ve just said suits them perfectly.
He does not state this in an ’in a perfect world all amps should sound the same and reproduce the natural signal fed to them and that is all’, but rather in the terms of that, today, if you are to compare two amps, being it as vastly difference as my comparison was or less, they will sound no different. He receives plenty of bashing for his BS statements like these, and I can now attest myself to how very different in sound an amplifier is capable of. It is as if I changed half of my components, and not just one. 
I have to add. When you see the amp in person, and especially when you feel the weight it possesses, your are at that moment certain that this amp cannot sound thin or weak. It is a true boulder, very hard to get out of the box even. The remote is probably the heaviest, most robust remote Ive ever felt for its size as well.
