Rowland 625

Hi Isvaldo, I do love GamuT products, and have in fact already have reviewed their CD3 for PFO ... I am sure I will review more GamuT products in the future.

You have just stirred my interest in ElectroCompaniet. I'll try to audition ElectroCompaniet amps at RMAF this coming October. If I like what I hear, after I receive and fully break in and evaluate the upcoming JRDG M925, I might try listening to ElectroCompaniet amps in my own system, and would contrast it with the sound of several SS amps, including M312, M625, and M925. I have simply no idea about the possible outcome.

Concerning M625, it is in my system right now, but I have not completed its evaluation. At this point M625 appears to be exceeding M312 comfortably in:

* Frequency extension;
* harmonic development;
* Mid bass linearity;
Micro detail;
* Three-dimensionality / solidity of stage and imaging.

M312 conversely still yields an overall larger image, which is quite understandable, given M312's higher power rating.

One thing extremely surprising about M625 is that bass controll is improved over M312, even though M625 damping factor is only 200, versus M312's 1,000.

Hope this helps.

but in the 3D depth the 625 was clearly outperforming the 312 ...
at least in the configuration I have heard them

Claude, you are absolutely correct.... For example, using my standard test track of the Old Castle piece by Dvorak played by Inna Poroscina, M312 induces a piano image wider/taller than M625 ... However, M625's staging/imaging is more coherent .... staging is deeper, and the piano has more 'solidity' than on M312, for lack of a better word.

I see Electrocompaniet is discussed. They are good amps, and very good value, especially here in Norway where I live. Just a short comment on Electrocompaniet vs Rowland: A Norwegian Hifi magazine called Fidelity, now has expanded to Scandinavia, tested the Rowland 301 monos some years ago and preferred them over Electrocompaniet Nemo monos.

Personally I think my 301s are more resolved than EC and expecially after I got Odin power cables on them they really shine (Odin was a HUGE upgrade!). Electrocompaniet is warmer, but less neutral, has slam, but still less authority, and also less microdetail. Electrocompaniet has great midrange though, but are not so extended and resolved in bottom and top frequencies.

Well... welll.

After 5 days my Electrocompaniet AW250R had a internal problem. As I don't want to fix it for my use, I'm going to sell the amplifier together with the 4.8 preamplifier.

So I'm going, slowly, to pay attention to the M625 as I have the Criterion.

But after I heard the sound of the GamuT and AW250R I'm afraid that JRDG hasn't the "feeling" and the "finesse" to make a "sweet for the ears" amplifier.

I mean something warm, because I find out that you can spent more hours listen to the music without become tired with a little bit warm sound.

Sorry my English, but I think the opposite word for warm in audio is Analitc. IMO the Model 312 has a analitc sound and a prefer a litle bit ( not too much ) warm sound. I don't want the M625 with a analitic sound.

Anyway, If anyone knows could tell me, please, the 625's Maximum Power Consumption at 4 ohms? Because I didn't find it in its specifications.
