Hallo! I from Ukraine.
I am sorry for my bad English.
You have created very interesting site. I very glad, that I have found him.
I searched the amplifier for headphones for mine Sennheiser HD565 Ovation. I very much like these headphones, and they are worthy the good amplifier.
To operate has decided so. 1. To make the amplifier itself. 2. To take on listening good amplifiers from different manufacturers. 3. To choose the best variant and if it is required to buy that him.
First I have been adjusted to buy Musical Fidelity X-Cans V3. He for a long time liked me. I have decided to take from the friend this amplifier on listening what finally to be convinced of correctness of a choice. He has given me the HD650 for the complete set.
By this time I finished work above my self-made amplifier for headphones. The author of the circuit I.Semynin. A class and, without the common negative feedback. It emitter repeater with gain = 0.98.
As appeared, it is completely unexpected this circuit has shown quality of sounding of very high level. And on so much high, that the question on purchase X-Cans any more was not …
Has most of all surprised, that this simple circuit on a kind possesses huge resolution and musicality. Any music carries away the sounding from first seconds. There is an impression, that the technical equipment does not accept any participation in construction of a sound picture. A sound very much both very transparent and beautiful. It is a lot of emotions and music nuances. Musical instruments at all do not prevent each other on any loudness. The sound is sated with paints and moods... Can play very gently and easy as water in lake, and then confidently and easy to blow up force of the sea …He always gives a different sound on different disks.
It is the best amplifier for headphones which I heard in the life. The result of me simply shocked. This circuit frequently discussed on many Russian sites and very high estimations allowed to her. Including Alex Nikitin (Creek Audio).
The circuit strangely enough simple also is made very quickly. So you can check up my words without special efforts. The unique barrier is the applied transistors. They can be found only in the former USSR for two reasons. These are transistors (2Т908 and 2T602) with the high contents of gold and made for a military. But in one of discussions Alex Nikitin recommended to use for replacement 2N3055 and BD139 (only Phillips!!!). He has told, that if it is impossible to find BD139 from Philips that better to apply BC639. He has noted, that only BD139 from Philips is original development. BD139 from any other manufacturers it is "fake".
I have applied entrance condensers M-Cap Mundorff. Necessarily, even for experiment, spend for this circuit 3 hours and 20 dollars. Very much it is pleasant to you, and will be strongly surprised.
The case
I have MF X-10D. More often, it appeared, that X-10D was not necessary. For me he became too appreciable in work hi-fi system. The decision has come at once.
Has removed internal contents X-10D from the elegant case and the new amplifier for headphones has placed in him.
