TFM-75 vs Sunfire Signature 600x2

Post by MRHP » Sun Feb 26, 2012 3:53 pm

Dont know if anybody has done this before but heres my first impression.

Although I have not given the 600 enough play time there are a few differences I noticed right away.

The 600 is slightly more musical with maybe a softer tone, it is pleasant to listen to. It also acts like its not working very hard to reproduce sound. The power is pretty impressive compared to the 75, its just not quite as muscle bound. It handles headroom with finesse and just has a very clean sound. The music seems to have a live sound.

The 75 is strong! I have never clipped this amp, never even been close, the needles rarely swing past 12 o clock. I have loaded it down with three sets of speakers before and it just seems to be at idle all the time. The headroom is what is most impressive about the 75. When a big note comes up it attacks with authority and quickness rather than finesse. As much power as it has its amazing how subtle it can be at times.

I cant decide between to two. One thing is for sure, Im enjoying the music.

How about a 600 x 2 on the mains, and a TFM-75 on the subs, if one had such a setup that could take advantage of both!

Especially since the TFM-75 has input level controls, helpful for setting the bass level.

Well rah its funny you mention that. Right after making this thread thats exactly what I did. I unhooked the PT-2400 and put the 75 on the subs. There wasnt much difference, the bass seemed maybe a little more lively if thats even possible. As I understand it both amps are nearly identical when the covers come off.

The 75 did however cause the CDP to skip a couple times when a bass note would hit. Did I mention I like alot of bass :lol: :lol: Got to see the 75's needles bounce way past 12 o clock for the first time ever. Those JL subs are quite unbelievable.

The next thing to do is put the 600x2 on the subs and see how that works. The 3 ohm load should cause it to pump out some pretty good power.

Well after getting the DQ-20's fixed I had to start rolling amps again. The above setup held true with 4 different sets of speakers until the 20's. With the 20's the 600x2 sounds great and I mean great...but...the 75 out performs it hands down, its not even close. With the 75 the music has body and incredible 3-D. The highs are silk smooth vs plain jane or even a little harsh with the 600x2. The bottom end is deep and has quick punch, and music seems to just fill up the room. Its by far the best sound Ive had yet.

I guess it goes to show you that matching components is key to getting great sound.

"I guess it goes to show you that matching components is key to getting great sound."

Yep; if not "key" (i.e., most important), at least a VERY big factor... Results sort of similar to mine for 42/45 vs 300x2. For one setup the 300x2 "won"; for another it was the refurbed TFM-42.....so obviously that's how I left them! Been hankering to try the 42 with my TFM-45 in mono block mode and see what that sounds like (with the 8 ohm epi 1000's of course; not the ~6 ohm sphere's). But I know most say the extra power is not worth it as the "sound quality" goes down...?

But that's great info MRHP; maybe SS Carver is still the champ (tube sound wise) vs Sunfire, but in general I'd say no. Plus the Sunfire amps are just obviously more "beefy" and better built....real "heavy duty iron"...perhaps excepting the 75...

That's what she said...

Maybe I will...but hate to mess with system...(if it ain't broke, don't fix it, etc.). Plus my TFM-45 has semi broken speaker terminals that have a tendency to not keep the wire ends "staid put" (especially the large QED Silver Spiral wire ends attached there upon). Plus with my "tribe" more power just equals "greater chance to blow up dad's speakers" ](*,) :x
