I plan on getting TAD CR-1 speakers (86 db efficiency, 4 ohm impedance) as my first building block of a computer-based, music playback system. TAD Labs recommends an amplifer with power ratings of 200 watts into an 8 ohm speaker and 400 watts into a 4 ohm speaker. I initially wanted to see if I could get an integrated ampilifer of this power rating to save boxes and cables over a separates preamp/monoblock solution but did not really see anything that had the power recommended. As I read through AVguide posts on DACS to become informed, I see that there are many DACS that will feed directly into the amplifier so maybe a preamp is not even necessary, thus narrowing the search down to the amplifier.
I have heard the CR-1 several times with PASS LAB amps and liked the sound so I plan to investigate this further. However, I read a posting in AVguide where the poster said that his PASS X150.5 or X200.5 amplifiers ran so hot that, in the summer, he did not listen to his system. Obviously, this would be concerning and unacceptable. Have others encountered similar heat problems in the summer?
I am looking for amplifier advice on the TAD CR-1. I value speed, transparency and soul. Neil Gader, in his review of the CR-1, found an EAR 50 watt tube integrated amplifer gave acceptable sonics but got preferred results when he swtiched to TAD LABS high powered amps with their added headroom. So it seems added power amplification will be beneficial.
