HiFi-Do E-mail Newsletter

Hello, I am Asai of Hi-Fi-Do record shop. I want to report sounds this time.
This target is a vacuum tube. It is 12AU7 also said ECC82. Customers often ask What kind of sound in the shop. Although answered by evaluation of an image at that time, It is not good. I chose the voltage amplification tube which can do easily.
	A reference set is the monophonic speaker system of Altec. and a monophonic set of McIntosh C8 and MC30. Then, I compared to play Solo Monk.
It is this Mr. MC30 that tubes are removed. GE is here as the basis. (From the left to the 2nd)
	One of the reasons that I also chose was that we had many kinds of 12AU7 stocks. It is the try listening of a total of five sorts.
At first it is active and Electro Harmonics (EREHAMO). This sound is Kachi for one word. The shortage of nuance. Low range is slightly insufficient.
	The next, its own country. Toshiba 12 AU 7. Having changed is low-range. It becomes anyhow somewhat large. The impression which is tight for a while. Although touch of sound resembles EREHAMO, I know well that the quality is going up.
Now, legendary men appear one after another from here. First of all, it is Terefunken from Germany. However, with no diagram mark. Made from Ei of Yugoslavia (It is the tube made after Terefunken withdrew from the enterprise and Ei bought the line. 7025 of the present RCA is called product made from Ei) The resolution of the sound of each itself is high. Resolution of low-range is clearly high. I was surprised because an outline has come out. It is amazing.
	Next, it is British MURADO. Considering a internal structure, probably the thing of the 60s. Sound impression is completely different. It is soft. A High does not have tightness, either, and although the low is also extended, it is not tight too much. I think the feeling of an analog in this listening.
And the last , this is the origin Terefunken. Containing a diagram mark. The sound of each claim. It is smooth and sharp. Conflicting monochrome lives together. Resolution is overwhelming. The capability to picture change of a sound is number one.
Although I reported and considered this time, an audio is very interesting. Even one vacuum tube changes sounds. PS. About GE. It is soft and, and yet, sound has come out firmly. I have been convinced that McIntosh chose GE. I thought again that sound of McIntosh has depended on GE.
