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!

jkull,

From what I've read the weak link in the 219ia are the preamplifier stock 12AX7s. If you are using the preamp section of the 219ia rather than a separate preamp that is a good place to begin tube replacement.

Charles-

I am using the 219 preamp section when running my oppo for digital listening right now.

Question... its a pretty silly one but.. I am looking to upgrade my phono as discussed previously. I am still using my marantz 7701's built in phono, but want to order a Decware ZP3 (SET) phono. When running this phono into the 219, or any phono for that matter, I am still utilizing the 219's pre amp correct?  Like, your phono does not act as the only pre (sound defining) in the chain right? Thus changing 12AX7's in the 219 is still a worthwhile move for my (predominantly) vinyl listening. The question is probably so dumb that it is confusing you.  Sorry lol
Yes, I believe that you’re using the preamp (line stage function) section in the pathway to provide gain for your phono signal .If Al happens to be still following this thread I hope he’ll correct me if I’m mistaken.I think the 219ia allows bypassing the preamp section via a "direct" connection thus using the 219ia as a power amplifier only option.
Charles
Jkull, like the majority of phono stages the ZP3 appears to not provide a volume control. Therefore to be able to control the volume you would connect it to one of the 219ia’s inputs that does NOT bypass its preamp section (i.e., to one of the inputs other than "pre-in"). And therefore a 12AX7 upgrade is likely to be worthwhile.

A follow-up regarding your earlier question about hooking up your sub. If you are willing to invest $207 (plus cabling) for that purpose, here you go:

And here is a link to the manufacturer’s datasheet:

Many other devices claiming to perform the same function are available for much lower prices, but in contrast to most or all of them the products of the Jensen Transformers company are frequently used and are well respected by high end audiophiles.

Good luck. Regards,

If Al happens to be still following this thread I hope he’ll correct me if I’m mistaken.
I was already composing my answer above when you posted this, Charles :-) And no, as usual you’re not mistaken.

Best regards,
