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!

I have the 219. Great amp. I played with the 12ax7s but ultimately went back to the stock. The amo is amazing as shipped. I have the rca and telefunkens if I get bored. Also, I have an EAR 868 pre that I use on the direct taps. The sou dstage gets more focused but not better. The LM pre is great. 
Glad to see this thread still active. I am having a real love affair with my 508. The addition of some NOS Sylvania VT231s in place of the Electro Harmonix 6SN7 stock tubes made a significant improvement in refinement and musicality. I just ordered some EML 300B XLS tubes, which I hope will take the amp to even loftier heights. It is truly a fabulous integrated, and it really whips my Daedalus Ulysses speakers into shape. 
The EAR 868 is very highly thought of in the realm of good tube preamplifiers. Quite a compliment for the 219ia preamp section competing so closely. 

Walter I'm curious to know how the EML XLS works out as a driver tube in your amplifier.  It's splendid as an output tube in my amplifier.

I am glad that you are all finding out the virtues of the LM gear.
I previously had the 518ia and found that the 12ax7 input tubes are in a configuration that one follows the other with the right hand tube being first. This allows the tubes to be mixed and don't need matched pairs!

I found that the 5751 gold labels black plate to be outstanding mixed with a Mullard 12ax7 long box plate. Strangely Siemens EL34s instead of the 6L6 driving the Psvane WE 1:1 845's. I was using a metal base Mullard 5ar4. After changing the coupling caps to Duelund's and adding Lundahl grid chokes the sound was outstanding compared to an already very good stock unit........

I have since sold the 518ia and bought the LM503pa mono blocks... man are they good! I have changed the coupling caps and added the grid chokes as per the 518ia. Replaced the signal resistors to the new Audio Note silver Tantalum's, they took a long time to burn in to the extent that they were almost un-listenable. It was worth the wait. I was using the Psvane WE845's and have now upgraded to Elrogs (fingers crossed they hold up, however they now come with a 1 year warrantee) This was a very large step up. Driving them I have the Takasuki 300b's and NOS russian 310a's. I look forward to some reviews on the WE NOS 310a's.
I have some Elrog 300b's on order.......

For rectifier duty I am using the Psvane 1:1 WE 274b to good results, however I may change them to sone GEC U52's.

The amps really amaze me driving jbl everest horns with a 2" B&C dcm50 paper compression driver (new take on an old RCA driver) on top of a 15" lenehan built bass box and a Fostex t500amk2 compression high frequency horn!


pixelplay,

Can you describe what you differences you heard in the 518 between just using 12ax7s , and the shift to a 12ax7 coupled with a 5751?
