I have a TA-15 that I purchased recently, and I just love it. It can do just about anything I need it to do. Overdrive solves all other issues. I like metal for the most part, and I live in an apartment, which I swear has tea bag style walls, so playing really loud through cabs at home, can be an eviction generating event.
The best experience I have had so far, was with a wide body, Rectifier 2x12 cab that I tested the amp with in the shop. It really did sound great and had lots of bass response. I'm not sure it is the right choice for cleaner tones though. The TA-15 has lots of bass on tap, so if that is what you are looking for, look at the recto cabs.
I have used the TA-15 with the single Black Shadow 12" built into my Studio .22 +. This also has a pleasing sound when going for higher gain sounds. However, I found that cleans were a lot more rich and had fuller midrange than with the recto cabinet. Not a bad option there. I have always like the sound of the Black Shadow.
Given that I am in an apartment, I have also tried the Mesa CabClone. 8 ohm version. First, let me say, that if you are expecting a simulated "cabinet" from the CabClone, you are going to be somewhat disappointed. If you read the documentation, you'll see that the device is intended to simulate a cabinet, mic'd with what I think is a SM57 given some side by side comparison with a real SM57 and an e609. Running the CabClone into Pro Tools, I find this both convenient and pleasing to the ear once my expectations were set properly.
The two mode CabClone modes that I enjoy most with the TA-15 are the open and closed back speaker + mic simulations. To my ears, the closed back sounds closest to the Rectifier 2x12 sound. More compressed, with better bass and treble response. The open back mode reminders me more of the sound of the Black Shadow speaker with a more pronounced mid-range sound.
I ended up purchasing a Mesa Wide Body Closed Back 1x12" cabinet with the Black Shadow (Celestion C90) speaker. Here is a short clip recorded with the TA-15 on Hi 2 running through that cabinet. It was recorded with an Apogee Mic 96k condenser microphone.http://downloads.jamlocker.ca/Mesa-Boogie_2016-04-09_20.44.22_T001_In1.wav
