I do not need too much power, and I want to purchase the A-150 amplifier, it will be my first amplifier from Emotiva. I want to know if anybody knows how many watts are in Class A, my speakers are JBL Studio Monitors with 93 dbs sensitivity, I will have them cross over at 80 hz to my great 18" THX PRO SUB. When I leasen to music I play at an average of 95 dbs in my seating are wich is about 10 ft from speakers.I had an Adcom GFA 535 with only 65 watts and it was more then enough, but it was time to replace, so I bought a Crown XLS 1500 for my JBL speakers; I like it but it does not give me the sound stage I use to have with the 535.
So I am looking into the Emotiva A-150 to hopefully use only in CLASS A up to 20 watts?
Thank you for your help.

Maybe less than a watt. If you want class A, the closest ones that do class A is the old XPA-2 gen 2 (not the gen 3) - 5 watts class A or so. XPA-1 L gen 1 and 2 - 35 watts class A. XPA-1 gen 1 10 watts class A. XPA-1 gen 2 60 watts class A. Pass Labs is also famous for making class A amps but they are pricey. I believe the Audio GD Master amps also work in class A though I may be wrong on that. They say the "gain stages" work in class A which I assume means the amp output. You should know that the majority of listening is done at about a watt. Only on the peaks can the demands rise dramatically. If you can find somebody selling the old Emotiva XPA-200, that imo would be a better buy than the A-150. The warranty transfers to you. Don't get me wrong, Emotiva has never made a bad amp, so you won't be complaining either way.

I am currently using a used Adcom GFA-535 in my family room system paired with a PT-100 preamp which I love. I bought the Adcom for $160 on eBay. My DIY Tango speakers are 87 dBs sensitivity and I don't listen as loud as you do (87 decibels normally ) . I have found that I like the older Adcom amps because they sound like Emotiva Amps. When I bought the Adcom 535, Emotiva did not have the A-150 in production. I have looked at the specs and from my past experience I believe that the Emotiva A-150 will do as well if not better than your old Adcom. It should give you the soundstage you are looking for. If you don't like it you can always send it back. You will find the binding posts on the A-150 much better than the Adcom. Hope this helps. Matt

Great info, I will look into, sometimes I think I am delusional in believing I can get a great amp at a low price just like back in time. Class A amps were never actually cheap. You might be thinking Class A/B. Class A amps means large amounts of heat. For instance my XPA-1 gen 2 when the class A mode is engaged consumes something close to 400 watts of power IN IDLE. The temperature is imo hot enough to cook an egg. I think it's north of a 100 degrees F. Prolonged touching the chassis will end up hurting your hand (that's what she said). So you can't really do class A without big (expensive) heatsinks. Also cramming a high watt class A amp in to a small chassis will increase the temperature. So the size and design of the chassis also matters. In comparison a regular amp will consume just a few watts in idle - a fraction of the class A amps. Now there isn't a huge difference in quality between A and A/B amps. What makes more of a difference is how good the amps themselves are. I notice larger differences between amps than between class A and not class A. Even though the XPA-1 L amps are discontinued - both the XPA-1 gen 2 and the XPA-1 L gen 2 are class leaders in price. To get the same specs they do (fully balanced, large torroidal transformers + no fans + large capacitance) + class A power will cost several times the asking price of those amps. You can't match the price they used to ask to any other amp on the market now or at the time. But....they are still not cheap. They are still available used on the emporium.

sometimes I think I am delusional in believing I can get a great amp at a low price just like back in time. In my experience great amps were never at a low price, it's just that when we look back their pricing seems cheap in today's dollars. For example, my first Class A stereo amp cost $300 in 1975, it had 10 watts per channel and sounded pretty damn good, playing through a pair of KEF Concertos (that I still own BTW). Due to 40+ years of inflation/CPI that's equivalent to around $1400 today. About what my pair of monoblock XPA-1L's cost. Quite frankly there is no comparison, in any aspect, build quality, sound quality, sound quantity etc. The $1400 spent today is way better than $300 spent in 1975. Cheers Gary

Just ask your doctor.

the chart above shows CONTINUOUS dB. If your AVERAGE exposure over time meets those criteria, I'd pay attention.
The very loudest (highest) levels have almost NO tolerance, time-wise.
I even recommend hearing protection when doing normal yard work.
I have FITTED Earplugs ($$$) and some cheap ear covers ($). I use BOTH when using firearms. The cheap headphones provide enough attenuation for running the chop saw, drilling and running the gas lawn mower. And still be able to hear SOME ambient noises for safety. Even those 'Buck A Pair' expanding foam types help.
