The image is not sharp enough Dan : I can't read the figures...
Nice try anyway ! Thanks !

Ian,
Not here with the 2301's !
I' m just considering a pair of tube monoblocks of 70W in class A and it seems that they are made for 8 ohms speakers. Their power would be of only 35 W but class A on 4 ohms. I wonder how low the impedance of the EB1i goes down and at which frequency....

Ian.......Not at all. I would simply like to know what the impedance and phase curve data is reporting. I love my PMC EB1i's. Were I ever to change them it would be for a pair of PMC IB2i's.

Guys, it just so happens that I also have been requesting this data from PMC for a few weeks now. I was on the phone with them this morning and was told they would get them to me by the end of the day. I requested frequency response plots for FB, OB, PB, EB, IB1 and IB2. I will post up here if I get them. I'll also request the impedance plots from the same contact.

Fingers crossed.

Jérôme.......I was disappointed in the clarity of the chart as well, but that's the way it appeared in HiFi Critic's web article. I tried reducing it's size to clear it up, but no luck.

Still, there is some information to be taken from the chart. It is good to see that phase amplitude and impedance follow each other relatively close.

No joy unfortunately. From Ian @ PMC:

Hi Joost, I regret the information you are requesting is not currently in the public domain.

I must apologise for the delay.
