Tube amps are a fancy.
Solid state amps give you a higher fidelity and will be closer to the original recording. Tubes will impart coloring which some people like.

So, dumb question, but for regular everyday use, would this make a difference? I love listening to music, but wouldn't consider myself an audiophile.

1. Your entire statement is false, 1% THD and below is completely inaudible to the human ear.

2. "The solid state will negate the sound of the tube pre" false, It's not uncommon to feed solid state power amps with tube preamps.

3. WTH is a phone input? Just run a 3.5 to rca splitter to use with a PC audio.

This thing is FANTASTIC. Really looks great and has very nice sound. It's a big step up from the cheap $20 tripath amps on Amazon. Gets very loud with some efficient speakers. Upgrade to 5654W GE tubes off eBay for $13 and you'll be getting a helluva lot of the advantage of high priced audio gear for about $60.

EDIT: Sorry, I don't have experience with this exact one. I had the 25W four tube model. I'm sure this one is also quite good, and less than half the price. This is basically a tripath amp with a LittleBear preamp built in and Bluetooth.

15W is more than enough for most environments, unless you really wanna blow out your large room with sound. Make sure your speakers are 90db or more efficient and you'll likely never complain about volume.

Can anyone recommend comparably priced speakers to make this unit really shine?

I bought that Logitech BT to feed amp like this without BT and here comes the killer. I have tube pre-amps, they just sound little different, all my childhood I listened to tube amps and like the previous poster others always touted transistors as better. Pick some magazine of 1984 and before.

The Klipsch 14Rs are usually on sale for around $110. They're very efficient and would match well. I prefer the sound of Polk, so I would go with the Rti4s.

Micca mb42 are comparatively priced and will serve you well. For a little more you can get the pioneer Sp-bs22 the well known bookshelves designed by Andrew Jones. At a higher end you can look into the Elac debut 6 or the Kef 300 series.

Someone correct me if I'm wrong, but the 6n2 tube appears to be similar if not identical to a 12AX7, which is a preamp tube. This leads me to believe that the power stage is solid state, thereby negating much of the coloring and "punch" you get from a full tube amp. The claimed 15 watts are transistor watts, not tube watts.

But for 50 bucks, its super cool just to see the heating elements glow (though no plasma like power section tubes).

For your 25W amp, the GE tubes that you upgraded to were for the small pair, or the big pair? Did you upgrade all 4 tubes and to what?
Do you have some links to read up on this?
Thanks in advance!

Do you mean the RTI A3?

At 15w, I'd expect the RTI A1 to be more closely matched.

You are correct, and I pointed this out last time it was on sale. I also note that nowhere in the specs does it say 15 watts/channel RMS, nor give the power output across the frequency response on which it is rated (yes, it does say the amp's freq resp is 20hz-20khz, but it doesn't say it can produce 15 watts RMS across the entire power band), so the true power output could be considerably less.
