JR has no Class D technology.
JR uses ICEpower, one of the most matured and developed Class D available on the market.
Not saying ICEPower is better, but it is certainly much more matured then NuForce.

what is the diff of "taste" or characters of the amps ?
- are they musical ? or simply dynamic, powerful, analytical, but little taste ?

Nuforce vs. Jeff Rowland

兩者我都聽過,比較之下,當然兩者都有class D amp的特性:唔熱,淡味,播什麼都唔Z軟,音樂整整齊齊唔亂,低音比其他名器無潛得咁低(但煲好後會有DD改善)

但兩者比,雖然兩者都用ice power,JR同Nu Force有自己的character,特別JR加左PC1後,更加唔同。所以唔好話一樣用ice power,就買最平的,一定要試。

class D amp又好,class A amp又好,各有好處

最好有幾百火唔腳軟,又有Class A音色,又好似class D唔熱,就完美啦

"""Nuforce developed their own amp."""

i cannot see jr not developing their own amp too.

ice power is developed by b and o as proprietary switching power supply, not amplifying

cpu8088 hing: JR did not develop the amp, it is ICEpower technology, so called Power Conversion. it is not just SMPS. B&O did not have any proprietary on switching power supply. Sorry. Please study www.icepower.bang-ollufsen.com.

Nuforce develeoped it own Class D amplifier, but not the SMPS, therefore they have different upgrade in order to improve the performance by changing the SMPS. The latest V2 however, is the new Class D design using same SMPS.

If you want class A feel, highly recommended you to try tube preamp however, you need to have very low distortion tube preamp. It will give you warmer, deeper vocal and more harmonic reproduction.

despite their very high power ratings, icepower modules do not control the bass very well, especially with big speakers.

Cary CD303/300 is still the current model, however, older model CD303/200 seems sound better.
