Hi guys good morning, After some long time thinking, I pulled trigger on a TA-100 Amp. It is a bit low powered, but do you think it is sufficient to drive a pair of SVS Ultra Bookshelf Speakers. If I need more power, I might go with TA-300 + PA-100 combo. I would appreciate any feedback. What speakers are people driving with their TA-100s? The SVS Ultra Bookshelves are rated at 4 Ohms. My listening distance is 2m away from the speakers.
thank you
Haris

Ive used the TA-100 to drive a set of BS Klipsch and a set of KEF LS50 which are 4 ohm rated and dip much lower. The TA does a great job with both speakers. It really will depend on the size of your room and if you've treated it at all. My tests were without treatment and they sounded great, so with treatments you should be over the moon! Please don't tell ANYBODY that I did NOT suggest monoblocks! Long store, PM me if you want more!  |

It'll be all right imo. Depends on your needs, but for realistic volume levels, I don't see why it would be a problem.

2 meter distance? That pretty much qualifies as 'near field'.
Unless the room is gigantic and you are in a corner of it, you should be fine.
my garage system with about 6 or 7 watts per speaker does FINE driven by an iPhone.
They call it 2x10 @4ohms / 0.1% distortion.
Speakers are nothing special, and I have Zero idea of sensitivity or 'response'.
I don't even know if they are 4ohm or 8 ohm or 'other'.

I've got the PT-100 connected to the A-100 amp I got from Emotive two yeas ago, driving a pair of SVS Prime Towers in a 28'x30' den. They sound great. Do I want a TA-300? Yep! Do I really think I need a TA-300? Nope!

If you have 8 foot ceilings, you are at Over 6000 cubic feet. A large space.
Depending on your listening habits and overall loudness desired, I doubt the A300 has the oomph needed to really bring it on.
That being said, the SVS towers are an easy speaker to drive. Reasonable sensitivity and no wacky phase excursions to stress an amp.
I just wonder about what is really a pretty large room with only the A100 doing the heavy lifting.

Personally I would suggest a XPA-2 but...

I have a TA100 powering my ELAC F5s in a 10 x 14 room. Listening distance is 7 feet.The ELACs are 8 ohms I think. It will get pretty loud. If you are buying it for the tuner. Don't ! Not that it sounds bad it's just that it is not user friendly to change the channels. I am not exaggerating.
I am stating though that it is the best sounding two channel preamp under $1000 that I have ever heard. No bullshit. I briefly hooked up my McIntosh amp & literally was BLOWN AWAY.So the amp has 50 watts. To me it might measure 80-100. Imaging is fantastic. Only criticism at all is you can tell highs are slightly rolled off. Sound stage is much smaller than my main system. You don't hear that last detail of the cymbal. It is the best thing you can purchase for $399..
I don;t know if it is the ELACs or The TA100 but they are a sweet pair for a small room. Buy the BT module. All listening is done with Tidal & Spotify. I call it my $1100 system.
If I could hear ELACs top of the line speakers I would because I am impressed with these under $600(pair) ones
Rambling here but I added some GIK sound absorption panels(2) and have to the front sides of the speakers and it tightens up the bass. Guess those that use these things are not full of BS

My reason for 'dissing' the A300 was the fact that its power @4ohms is taken 1% distortion which means actual / usable power is somewhat less. Dynamic headroom Over and Above the RMS power is also quite limited. Probably 1db or less. Given that the room is very large at OVER 6000 cubic feet, I just feel that plenty of 4ohm power is what is needed. The current A100 is only 80 a side @4 with NO distortion specified. A bad sign, IMO, but it IS after all a very budget piece. Just not for a 6000 CF listening space. I suppose if 'pressed' the A300 would work for me, too. At 300@4, but with the higher distortion, that is probabbly about +6db or more against the A100. |

Power output at maximum wattage / maximum distortion is completely academic. Nobody (OK, almost nobody) EVER listens that way. And if they do, their hearing is so far gone that the added distortion doesn't matter.
Most listening, in most rooms is done at less than one watt. FACT.
At that output, there's not a bit of difference between the TA-100 and a pair of XPA-1s. Now at this point, the "but peaks require more power" crowd will jump in claiming that you need 10x the average program power for clean crescendos. And they're right. That's still only 10 watts. Still no difference.
So don't be afraid of "low powered amps." They work just fine. They lack the ability to give "mine's bigger than yours" bragging rights to your audiophile buddies, but the small amps work just fine for everyday listening, regardless of room size.
Want to throw a party? Buy an inexpensive used "pro" amp - nobody cares about sound quality at "P-off the neighbors" volumes.
20 to 100 watts is sufficient for almost any speaker at almost any reasonable volume (and I might even argue that those numbers should be 10 to 50 watts). Period. Really. Really.

I mixed up two posts above.
The OP is almost a near-field listener. No issues at all with the '100 series amp.
His '2 meters' works out to less than 7 feet English measure.
However, OldSchoolPolk, above has a HUGE room. His SVS Tower speakers are 87db sensitive. Not bad, but
the room is huge. I think THAT'S where I was headed with the 'more power' thoughts.

Some people should spend more time listening to music & less time calculating & posting.
Isn't that the point of great audio gear?

I have a TA-100. I also have our fire-breathing XPA-2 Gen 3. The two are more similar than different sonically, with the Gen 3 having a small edge in detail, transparency, and subtlety. The TA-100 is really, really good. For the money it's incredible. I have never noted a "rolled-off" top end with any of the famous-name speakers I have at home which include Thiel CS1.7s, KEF Q100s, Klipsch RB-25s, and Def Tech StudioMonitor 350s. However, I do have an amp that sounds just slightly 'brighter' with all of them, and that is my JOB 225. I also have a very 'warm' solid state amp, a Hafler 9270, and it is also warmer sounding than the TA-100, which leads me to think that the TA-100 is an excellent compromise between 'bright' and 'warm' sounding amps, and among the amps I have, it's probably the best stab at the middle ground of neutrality.
Klipsch La Scalas + Two good watts to rub together = Deafness. Most people don't realize how little power their system actually needs to get really loud. A sensitive speaker like our 91dB-sensitive T2 towers only needs a quarter watt to deliver 85dB levels, which are where in my own listening, I start thinking "it's pretty loud" - clean, but loud. It's little wonder that they had no trouble dishing out statement home theater levels and sound quality in our lauded AXPONA demo. What those extra watts get you is more dynamic range - put simply, bigger and more effortless hits from your music.

Rory,
Ever try your La Scalas with the Parts Express DTA-!? Very low power, in keeping with the high sensitivity of the Klipsch. I'll bet it's amazing.
Pretty inexpensive experiment. I use the DTA-1 in my garage to good effect, using only the Wall-Wart for power, not the AA batteries and an iPhone as source.
What most persons don't know is that even hugely sensitive speakers like the La Scalla are still <2% efficient.

I am using my TA-100 with Def. Tech SM 450's, as my desktop system. They drive them with ease while sounding truly beautiful. I am using the USB input from my computer, and they can get pretty loud, yet nice and clean sound, not fatiguing.
I also have the CD-100 hooked up to it, & I really have to dial the volume pretty low when using the CDP, but the sound is really nice to my ears.
I debated before ordering the T-100 , but I am glad I did. they can drive much larger speakers with ease too, as I have discovered when I hooked it up to my JBL 590 's Towers: no signs of under powering, and can achieve clear and detailed highs, with a enough power to deliver a good low end punch.
disclaimer: IMHO, YMMV.
