The F3 is a better amplifier than the ACA. I have built them both. The ACA is a simple circuit amplifier designed by Nelson as a diy project for a beginner amplifier builder to get a taste of what a class A mosfet amplifier sounds like. The F3 uses what is called power J-fets which also the more modern Firstwatt J2 uses. If you want more details of the F3 circuit you can look here. https://firstwatt.com/pdf/art_zv9.pdf The Zen 9 from 2006 is the same circuit retailed as the F3. Both are very good sounding but if hearing good enough you will hear a difference in the F3.

There are Y-cables that split the input signal as well as what Peter P quoted. Not the best way but will work.

Just to add, LaScala's have been marketed for home use for around 4 or 5 decades. One would think good engineers would know what is expected for home use after decades being sold for that purpose. The Jubilee speakers have roots in pro use as well.

They make Y cables to split the source input enabling the use of a sub with the tube amp mentioned. Not the best way but it will work. For me bigger horn bigger sound and the LaScala has a larger horn than the Cornwall. Give them some time. There is nothing like horn bass.

Like yourself, I do not care for bluetooth or usb but both are something many would consider necessary before considering purchasing a turntable. I gave receivers to my grandkids in college and the first thing after speakers they bought was bluetooth where they can stream from their phone. Chinese I am sure but most electronics are these days.

A few days ago I got an email about this new turntable from Parts Express. Looks good. Perhaps a member will pick one up and give review. https://www.parts-express.com/Dayton-Audio-TT-1BTW-Belt-Drive-Turntable-with-USB-Bluetooth-Audio-Technica-AT-VM95E-Cartri-300-363?quantity=1

Good review from a member. Hard to go wrong at that price. The tubes add a touch of 2nd harmonics which is always a good thing in my opinion.

On a tight budget give these some consideration. Positive reviews and on youtube. Do not expect decades of use or $5K sound though. No personal experience. https://www.parts-express.com/Dayton-Audio-HTA100-100-Watt-Stereo-Hybrid-Tube-Amplifier-with-Bluetooth-300-3848?quantity=1 https://www.parts-express.com/Dayton-Audio-HTA200-200-Watt-Stereo-Hybrid-Tube-Amplifier-with-Bluetooth-300-3850?quantity=1

The data sheet says all a designer or tech needs to know though.

Capacitor talk in a thread on this forum seldom ends well.

Exactly why did you post the amplifier you are using on one of my post. I have no desire to have a conversation with someone being irrational not believing in test, data, facts and truths. Find someone else to annoy.

I do not think you will be disappointed. Old reliable audio company for those that can afford them. You can depend on it lasting for decades as well.

Forgot to post Firstwatt site showing damping factor. You will have to do some simple math described at the bottom of the page. https://firstwatt.com/prod.html

Does this mean yo do not want to know the truth? Just how is one to determine power usage if one does not use basic electronics and test equipment? Only way I know how to test the performance of an amp is with test equipment using basic electronic skills. I test all of my amplifiers before I am through with them. An ear can be fooled and the amp could be distorting and one will never know it unless they run some test. Happens all the time. Unless you are convinced to run some test you will never know the true power usage. Guessing and hype is just that. Home usage using our speakers require very little power. I hope all members consider quality over quantity when considering an amplifier with Klipsch speakers. I seriously doubt you believe what I say because you are making the discussion personal between us. No problem, I still want to be friends that disagree.
