My JRDG Concentra II is better than any seperates I have owned, including Sim W5, Plinius SA100, Krell KAV250, Classe CA201. More musical and transparent. Better soundstage and details.
Separate preamplifiers and power amplifiers have long been considered standard audiophile fare, but sometimes the economy and convenience of an integrated amp can't be beat. Have you ever used one?
In the proces of choising a component, a compromise is part of the story. Factors like, quality needs,space at home, AVAILABILITY of components,level of knowledge and information, budget..etc intervene in this procedure of decision. I think that an Integrated may be a good com...promise !
I ran an Exposure Super XV integrated for a few years and loved it. It replaced a separate pre-amp / amp combination where the motivation was to reclaim some real-estate in the rack. I found the Super XV to be more musically satisfying than the separates, as well. The Super XV integrated has since been replaced by Exposure separates.
I initially bought my integrated amp (Krell KAV300i) because of the great reviews, the reputation of the manufacturer, and because I did not have the cash to go with even moderately priced separates. Since then, I have added a separate amp and used the pre-amp outputs of the 330i. I am upgrading the 300i to a stand alone pre-amp and will use the 300i in another system. I think integrated amps are great. They offer top notch quality, as well as more than adequate sound reproduction, when combined with a decent front end and a nice pair of speakers. I will never sell my 300i. Screw surround and home theater. I'm a two timer for life (channel one and channel two).
For years, I powered my ADS 810 speakers with a 40Wpc Kenwood amp. Don't laugh! Paired with a Dual belt drive table and a good cartridge, the sound beat systems with lots more power and higher cost. Currently, I use that integrated amp for my PC speakers and headphones. With the headphones, there's so much capacitance in the power supply, that the phones will keep playing for several seconds after turning it off. But then, in the '70s, a good 40W amp had a real power supply. Not like today's "100W" receivers. Other than that, I like the simplicity of the integrated, but for an audio system I prefer the preamp/amps route and for a video system I prefer the video preamp/decoder with separate amps. I think the integrated unit is a dead-end nowadays.
I am using a Densen Dm10 integrated, which replaced Naim seperates. In every musical sense it was an upgrade. The whole sound became more relaxed , fuller, and had greater retrieval of detail. The Densen now lives on a Phase 4 Mana support and can embarrass some rather well-regarded pre/powers.
I use a Rotel RX950-AX receiver in my system, which is budget but meets my needs. Other equipment: Rega Planet CD, Acoustic Energy Aegis 1 speakers sitting on Target stands, NHT SWP2SI sub-woofer with outboard 100W amp, Systemdek IIX turntable with Goldring Prestige gold cartridge, Magnum Dynalab outdoor antenna, stock interconnects and Radioshack "Mega" speaker cable. What I like about the system is the fact the NHT amp does the heavy lifting, such that the 50W the Rotel reciver puts out is adequate for driving the Aegis 1's. I also like the fact that, for a very reasonable price (~$500 at time of purchase), I got a very reasonable phono stage and tuner section. By purchasing a budget system, I feel absolutely no pangs of guilt spending lots of money on software, including those gorgeous but expensive JVC XRCD CD's. And did I mention that my system sounds pretty darn good? Happy listening.
