What's the main difference.........

Post by Audiophile_719 » Thu Jun 23, 2011 11:32 am

Good day gentlemen. Just a quick question out of curiosity. I am seeing a couple of amps here locally for sale and I really don't know the main difference between the two.

They are the TFM-35 And the TFM-35x

Could some of you knowledgeable gents help me to understand what the key difference is between the two ? Thanx.

The 'x' model meets THX certification criteria, which means it will output 100 watts at 1 volt input. Doesn't mean jack squat, really.

X model doesn't have variable output knob on front. They both sound the same otherwise.
In reality, it only matters what it sounds like to YOU!!!

Thanks alot gentlemen !! Very informative. I may just have to pick one of these things up. I still haven't gotten my TFM-25 repaired yet. Right now I am running a small PM-300 on my equipment.

Thanks Chauss ! They are the Infinity RS1 b 's that I got off someone hard up for some cash last year. I am currently gathering funds to purchase a set of Infinity Beta's.

It has always been my understanding that the TFM-35X did not have the 1 ohm resistor as well, thus sounding more like an SS amplifier versus it's non "X" designation counterpart. It was taken out to meet the THX standards if memory serves.
In search of accurate reproduction of music. Real sound is my reference and while perfection may not be attainable? If I chase it, I might just catch excellence.

The best way to enjoy digital music reproduction is to never listen to a good analogue reproduction.

I'm not positive about that.

& I think there was slightly more to the "t" mod in these than the 1 ohm resistor....

To earn the THX badge, a power amp must be stable into impedance loads as low as 2 ohms and have a fixed input sensitivity, which makes it easier to set the reference (85 dB) volume level. I believe that standard is an input of 1 Volt RMS must produce an output of 100 Watts into an 8Ω load.
It should sound like it isn't there!
