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!

 First off, I have no experience with LM amps yet.  Secondly, it seems as if no one here has shown real experience with a properly updated MC225 which surprises me, so I would like to throw in my two cents.

I have used a Terry DeWick updated Mcintosh MC225 with upgraded Klipsch Chorus II or Tannoy dual concentric for several years, and the sound is sublime.  The amp was completely rebuilt from the power supply thru the signal chain and I added some Cardas RCA input connectors.  I experienced a full bodied, multidimensional, and lifelike presentation of the music that stays very true to the recorded material with this amp in the mix. I love it! The amp is dead quiet unless you stress it with extreme volume levels or with inefficient speakers.  It is well know among vintage Mc tube equipment enthusiasts that McIntosh and your Klipsch Cornwalls make beautiful music together.  Mc225 has more resolution from the bottom to than found with my Terry DeWick updated McIntosh MC 30s(which are incredible amps no doubt).  This is probably because of the solid state rectified power supply in the MC225. 

Overall, there is a very well balanced sound from this little amp and a lifelike presentation of the music.  I love the sound of the Westinghouse 7591 output tubes, one Telefunken smooth plate ECC83 in V1, Military Mullard CV4003, and RCA 12bh7.  I have a hard time believing you wouldn't be impressed with an updated version of this amp with a good set of these vintage tubes.  Hard to go wrong with properly restored vintage McIntosh for pure musical enjoyment IMHO, as always YMMV.  Check out Jeff Day's blog for more good info on vintage McIntosh.
