A100 update

[hondaman01]

Hello Emotiva.
An A 100 owner here.
I been running this amp now almost a year now, FANTASTIC!
Speakers are Cervin Vega R30. 97db efficient. 5 to 250 watts. Used mostly, ohm L used off and on.
And some not so great JVC D 301,S.
The Vegas work great, as expected.
The Ohms are great as well for bookshelf system. But, the not so great JVC 60watt 4ohm are surprisingly nice. Not so much overbass. And With the klipch 12 sub. It's like NICE EXPENSIVE SOUND.
THANKX GUYS.
The R 30s play loud and very bright.
The Ohms are smooth well balanced rich with nice bass.
Cabling is monster from amp to sub. 12ga stranded from sub to speakers.
K mart DVD for CDs.
Technics cassette.for analog.

Hello All.
So I been using this a100 now for couple yrs.
It's real nice!
Drives speakers well.
Headfones nice.
But to tell u, the old rock stuff, it's I just can't find the full potential of this amp!
But... When I play carbon based life forms ,this really shows the FULL potential .
So guys try some of this ,
Old rock is old.
Let me know I can take criticism.thanks

Curious to know what you define as "old rock" and what kind of music "play carbon based life forms" is.

That is some artist that played on my phone. It's like ambiant bass sorta Mello but not so.

Hi I'm new to the Emotiva forum and love their components. I own  PT-100 Preamp/DAC, a A-100 Class  A/B Amp/Headphone amp and a ERC-3 that all work great.

I just had my A-100 serviced because the DC-Offset was not functioning properly. Emotivas Techs fixed the issue and shipped it back in only 7 days. It now works like new again and I have been burring it in so this will not happen again. 
Because I have two main headphone amps and a hafler DH-500 that has been upgraded I usually only use my A-100 as a high output headphone amp and have the Pre-out  split  with Y adapters to allow me to run either my A-100 as a headphone amp or my completely upgraded Little Dot MK II with matched super power tubes and a few different matched pairs of driver tubes to roll as I see fit. The Little Dot MK II can be up-graded to sound better than jsut about any other all tube headphone amp I have ever tried and I have tried a bunch, The Schiit's Audio mangi 2 and the Asgard II were both o.k. headphone amps but could not match the performance of the A-100 set in high output mode.    

I use Sennheiser HD-650's about 75% of the time since I live in a apartment and I don't want the cops called on me or to be rude to the nice couple that lives below me.

I was wondering if anyone here knows if the A-100's gain control can be set at full output without clipping the Amp? Like I stated I'm currently running my A-100 as both a main amp and as a high output headphone amp that puts out 1.3 watts into a 300 Ohm load or 1,300mw. So I have a white press on decal that shows really where the gain control is set so I don't blow up my expensive headphones. 

I just need to know if I can put the gain of the A-100 to full output when it's used as a 50 watt per channel main amp into 8 Ohms? I have Definitive Studio Monitor 450's which are large bookshelf speakers with a sealed enclosure. They have a main 6 1/2" mid bass driver a 1" aluminum dome tweeter and a 10" passive radiator that really helps them get them to about 35hz 4 without a powered sub. The specs claim my 450' can get down to 26 HZ but I know that is not accurate. They may actually get that low during testing but the low bass can't play very loud if indeed they do get that low. The 10" passive radiator really helps with bass performance but being realistic I would say they can get down to 40 hz

So can I safely put my A-100 at full output without clipping the amp with my 450's that are rated at 90 DB S.P.L.?  Thanks for your time my fellow Emotiva lovers. Sincerely, Steve L.

P.S.: I had both my A-100 serviced and my ERC-3 needed a new transport when it failed about 10 days ago. Emotiva was able to repair everything within less than 7 business days and they include a extra 6 month warranty on top of whatever you have left on any component. Great company and great people to deal with.

Yeah me too, though I think Silicon based life forms get the harmonies and rhythms better. 😁😁😁😁🙃🙃🙃😁😁😁😁

I may be wrong but I think your A-100 volume knob is not an actual preamplifier which increases the gain. It just reduces it from whatever the signal fed from your PT-100. So think of it as something that decreases the signal.

So the real question is how much output is being given to the A-100 from your PT-100. If I'm not mistaken the A-100 has about 29 db of gain. If it can put out 50 watts of output, it would likely not take much output power to drive the amp past its clipping point.

So I think the answer is that yes it is possible to clip your amp when set at maximum volume. But .... it's also possible to clip your amp when its set at less than max volume. It all depends on the input signal. However...you're going to KNOW when the amp is clipping. It will be rather obvious. It's going to go from a clean sound to some distortion. For the most part though you should know that your listening will be done at about 1 watt of power or less. That's the average power used. At peaks for very short periods of time the amp could demand lots more power. But I've found that it really doesn't take a whole lot of power to power speakers to enjoyable levels.

Here's an example - we tried the A-100 in a really big living room with speakers of your efficiency. They had no problem filling the entire room with music at lifelike volume levels. Then we dialed back and used a tube amp which only did between 7 to 12 watts of power. And still the result was the same.
Home theater is a bit different because here there are serious demands on the amp which can cause clipping. But for music, I think you'll be fine unless you are a party machine. Also Emotiva amps can deliver more power than what they are rated for for brief power outputs. So even though your amp pushes out 50 watts of power. For brief periods like that found in music, it can deliver a good bit more than that.
