New Roof Construction I'm so impress!!!

I really love it!!!

The monoblocks Jeff Rowland model 7 last model , are absoluteky the est if the best in Audio hi end at any level of the price and with constructive and manufacturing quality at top 5 stars. Infact them having been built in very few examples and handcrafted by hand. The sound is the sound is clear but never tiring, with a slight note of warmth, it has a unique touch of delicacy and a refined and precise intelligibility, an absolutely unlimited dynamics, combined with great control. Absolutely the best solid state I have ever heard in my entire audiophile experience. A sonic masterpiece that disappears when it plays, that makes the best of both solid state and tube solutions. 10+

For me the best ever made Monoblocks amplifiers.. Very versatile with numerous connections of preamps and electronics in general. Absolutely amazing!

The best Power amplifier ever made!!!

In over 30 years of experience in Audio hi hand I have had and tried many of the best amplifiers, such as mark Levinson 23,5 and 20.5, Threshold s 300 and 800 and the Top of the line SA1, Accuphase a 50v, p 500, p600 , p 1000, M 100, mcintosh mc 252, mc 402, mc 602, Nagra VPA 845, Moon W5 and Moon W8, Onkyo grand integra M 510, Classe Audio D3B, Line Magnetic lm 219 ia, Pass Labs x350 and many others, but the Jeff Rowland M7 mk3 transducent. Unquestionably, the Rowlands possess a gorgeous high end. The extreme top is, in fact, the best I've ever heard from any amp — either tubed or solid-state. It is very clean and airy in character, with a touch of sweetness, not syrupy and rolled-off as I've heard from some tubed amps. The mid-treble and presence regions, down to about 4kHz, are also exemplary: clean, very smooth, and a little on the soft ide. Unquestionably, the Rowlands possess a gorgeous high end.

The mid-treble and presence regions, down to about 4kHz, are also exemplary: clean, very smooth, and a little on the soft ide. I had the result was a virtual transformation; the sucked-out middle range came up, the low end took on added authority and heft, and the already superb high end was unchanged. The amp now sounded superb on every loudspeaker I had on hand, including the MartinLogan Monoliths, with which the laid-back midrange of the Rowlands had mated so poorly in earlier incarnations. As a result of these latest improvements, I was prepared to give the Rowland 7 an alone-at-the-top recommendation, despite its seemingly outrageous price, but something changed my mind. As of now, I can only say that the Rowland Seven/II (or is it III?) is only one of the best amplifiers money can buy.

I've had the Series II incarnation and the latest version (transimpedance) for several years.

First of all:
Building quality of Rowland is a match for other highend manufacturers.
Have had the bigger Krells, Levinson's and Threshold's but fit and finish of Jeff Rowland is simply the best.

Luckily these amps do not look good only but are very powerfull, sweet and musical sounding products.
Together with the Threshold SA/1's and Levinson ML-2's I find this amp the best of the crop.

I can recommend these amps without any hesitation.

The Model 7 is unbelievably good. Unbelievably well built. It is also virtually unllftable at 50+kg each monoblock and is recommended for people who live in burglary prone neighbourhoods. No one is going to run off with them.
Yet the sound is warm, natural, delicate, insightful and musical- it sounds real. The dynamics seem unlimited and unstrained. I use valve amps generally and I can't tell any difference. No solid state signatures. The Model 7 has that clarity and tonality that makes good valve amps so enjoyable. The difference is in the power and control. And they work with any speaker load I've come across.
All round best amp ever? Possibly, but I haven't heard or more importantly lived with every other contender.
If you ever find a pair, buy them and don't tell anyone else. They are a bargain. And, as noted above, get a Coherence pre as well. Jeff Rowland excelled himself in the conception of these amps and his theory works brilliantly in practise. Imagine what the new price would be today for these behemoths.........

I am a former designer of amplification equipment, designed a hybrid trnsistor array back in the 1970s for IBM.
The Rowland Research Model 7 is perhaps the finest amplifier ever conceived.

It has the power capacity to play any speaker with sonic accuarcy heretofore unknown. It can be as warm and authentic as a vacuum tube amplifier and get just as hot (BTUs) too.

IT is best served with a speaker that can take advantage of its ability to deliver sufficient power for any musical passage. working best with active electrostatic speakers like Martin Logan's CLS-IIs. THese speakers demand gobs of power and will alter their impedence during the course of any musical passage. The Model 7s can deliver from 350 watts at 8 ohms to a whopping 1200watts at .2 ohms without changing any settings further with built in power conditioning you plug the Martin Logans right into the Amp's power supply.

For listening to jazz there is no better combination, the Logans and model 7s give a live sound stage with extremely accurate 3 dimenisonal imaging even in a stereo (2channel) only envirnoment.

I also recommend matching the MODEL 7s with one of Rowland's superb Coherence preamps.

I send my Model 7s and Coherence preamp back to Jeff Rowland once every four years for calibration and updating, there is a high cost of freight but Jeff usually finds something new to tweak evrytime and rarely charges for the enhancements.

the last time internal wiring was upgarded to a silver gold alloy and the sound improved dramatically.

i also recommend using the highest signal integrity cables available. Cardas usually workd very well. And in a fully balanced set-up if you can.
