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!

Hi Charles,
I had and loved the VAC Ren 70/70 for several years, but sold it along with the matching preamp and then bought the Devialet, which sounded "good" but in the end just did not engage me emotionally. In short, I missed that old tube magic and just was not spending any time listening to music. At that point, convenience and technology are beside the point.

Eventually, I would like to find the VAC's little brother, the 30/30, but until then, this LIne Magnetic appears to be a real winner. Once it breaks in, it will be fun dialing it in with the right tubes. It is a powerhouse, that is for sure.

I really wanted to hear those Frankensteins of yours, but couldn't find anybody nearby who had them. Luckily for me, there is an LM dealer just a few hours down I-40.

Have a good evening.

Chris-
I know I am not as well rounded and experienced in the variety of amplification out there. But I can tell you that everything I've read about these amps is displayed with this 219ia. I listen to everything from jazz, to Fiona apple, to behemoth. It is doing is all with grace.

You read a lot about single end triode amps being magical with vocals and acoustics, and this is so true. However, I am loving how amazing something like speed metal sounds at lower volumes. Seperation in instruments, cutting midrange that is smooth, and the worry of bass control with it is out the window. Bass is great, and that is even with NO negative feedback (I prefer it off).

I am considering rolling some tubes now. Not the 845's but maybe the 12AX7's. I'm open to advice on where to start!

@waltersalas I can't speak for your Line Magnetic amp but in my own amp a PP EL34 I picked up some Sylvania 6SN7 GTB's from seller realdeal on here back in March and they sound fantastic. He seems to have more for sale:

No affiliation other than having made a satisfying purchase. Happy listening and congrats to Jkull on your new amp have fun rolling those 12ax7's!

Hello Walter,
Some people say that the VAC REN 30/30 may be a bit sweeter and organic than the more powerful 70/70 (if you don’t require the additional power). I can’t comment on that comparison but I believe that both are terrific amplifiers . The Coincident Frankenstein is superb for my needs however I feel that the LM 508ia is also superb and a wonderful match with your Daedalus Ulysses speakers.

A friend of mine had the Absolare Passion Signature 845 PSET mono blocks and we listened to a variety of 845 tubes. NOS RCA,Elrogs, Shuguang, Psvane Hifi and their W.E.Replica version. The best sounding were the Elrog and Psvane W.E.Replica, these two stood out without question in our opinion.

Elrogs are Uber expensive and can have some reliability issues. The W.E.aren’t nearly as costly (although they aren’t cheap either) proved to be very reliable and sound excellent. Overall in terms of value and absolute sound quality I enthusiastically recommend this tube. Your 508ia is high caliber and will exploit the top quality tier of tubes.

Walter,
I just realized that I am talking about the 845 and your 508 uses the 805, Oops! I'm thinking about the 219ia that does use the 845. I don’t know much about the 805 but if Psvane makes one I’d look into it. Their upper tier line of tubes are consistently good.
