The first is a $11k integrated amplifier from the R series.
Musicfx bought one of these and he had compared the T+A to a comparably priced Pass labs integrated and he ultimately purchased the T+A over the Pass Labs and another integrated amplifier he was also auditioning.
The R series use much of the technology of the more expensive HV series but uses a superb switch mode power supply to lower the cost. The PA 2500r was amazing sounding when we had one on display it has a very purcuasive and rhtymic quality coupled with a huge soundstage.

T+A is the largest electronics manufactuer in Germany and they have the resources and raw engineering talent to create some very interetesing and very high performing gear.
The more expensive HV series integrated was compared to $120k worth of Ch Precision gear, in TAS and the reviewer Allan Taffel was having a hard time telling the difference, so the $18k PA 3000 HV integrated is one fantastic ampliifer.
The HV concept which T+A created runs solid state devices at very high rail voltages the same as tube products and the incresed voltage enbles the transistors to become more linear amplification devices reducing distortion and creating a very tube like midrange.
The T+A stuff is very powerful, with a huge sound stage, excellent transparency, but without being sterile, and the bass is very punchy build quality is fantastic, is the the styling and feature set.
The latest T+A integraed the HV 3100 which is an improved version of the original less expensive PA 3000 integrated was compared with a $45,000 Dagasitno and the less expensive Vitus.
The reviewer found the 3100 to combine the best of both of those companies products and the $22k T+A integrated was considered to sound as good as the twice the price D'agasitno Momentum product.

So if you are looking at a destination level integrated this is one company I would look at strongly.
