Gaz,
If you get the chance can you run the mini t as a power amp and put the tissie in front of it and give your impressions? Let us know how the psu performs, im tempted ( even though my lead acid love in continues)
Brian,
Spill the beans...ye think a couple plumbed up to my mini ts would be good ju ju!!!

Brian bought one of these www.ebay.com.my/itm/30W-DC12V-HiFi-Linear-power-supply-Regulated-PSU-for-DAC-headphone-amp-CL-215-/111544612626?pt=UK_Sound_Vision_Amplifier_Parts&hash=item19f893b712Its remarkably good value for the price, component quality is superior to that pictured, proper 230v R-Core transformer, decent rectifier diodes, Nippon Chemicon "KMH" input capacitor & Panasonic "FM" output capacitor with a WIMA film on the output. The internal pot has good adjustment so you can play around with the output voltage between 12VDC>15VDC. Admittedly its not the most powerful but is perfectly fine for a TA-2020, I'm yet to be sold on using a 160VA+ transformer but will be trying different values with the PCB I'm expecting so we'll see how it goes. Interestingly if you look at a Lehmann Stamp which also use a TA-2020, Lehmann don't use a regulated supply at all but a simple CRCRC... Thats another avenue entirely but if there's interest I don't mind making one up along with the other for people to try. |

My only experience is buying a Muse TA-2021. Firstly it had less ability to drive speakers than I've ever encountered in an amp: Even 6 watters. Secondly it had an innate ability to rub me up the wrong way. It seemed to mis-time every piece of music it was given, making the least of even the most enjoyable tracks. I didn't find a single bar of any music remotely enjoyable. I think it was only £35 or so and I honestly felt it was overpriced. I have no idea if the Muse is typical of T amps. Very sensitive speakers may help address the low power but I can't see there being a change to the feeling I had that it was just plain "wrong" in the way it presented music, especially timing. Hopefully one day I will hear a T-Amp that confounds my current experience. I'd never rule it out because hifi has a delightful habit of confounding expectations and producing delightful surprises. The Mini-1 I have on loan is driving a set of these:  Good weight in the bass bass, plenty of drive. The New Mini-1 might surprise you. Paired with speakers that are not difficult to drive it can sound very good indeed. |

I do not have a tamp at the moment but probably get another Mini 1 sometime so be very interested to hear how this develops and what it is like against a battery set up |

What about Mini Ts coupled up to your plumbs? Always good to look at different options and some variation.... Ill try the mini T as a power amp too. Will do mate. |
