Hi,
Are considering buying this SUT. Could it be anyone out there have measured the DCR of the primary and secondary coils - this is of importance when it is intended to be used with a Denon DL103.

Hello Johannes,
I have the 4722 and two pairs of the Cinemags. I also had the experienced of using the 15095A. On DL103's, I found that the 1:10 (20dB with 470 transformed Z) is not enough as far as gain is concern and that was the reason why I sold mine and kept the 4722. The Cinemags are a little more dynamic but the Altec's are very smooth, very pleasing especially on Jazz or small ensemble music. For material that requires a lot of punch, to me, then the Cinemag has the edge.
The problem I have with the 15095 was that if I try to load the 103 at say 150 ohms, it seems not to have the right amplitude of the signal to better drive the phono preamp, whereas the 1:18 at approximately 150 (145 thereabouts, no resistors required)has a lot of gain to spare. You might want to consider this scenario in your decision.
goodluck

DIY, all the time!
I would think that reflected Z would be the main concern. It is a 10X step up. I use an Altec 15095 with a denon 103 and it works well. The only drawback is that it a little short on gain. If you have a line stage or phono-pre with enough gain there is no problem. A passive line drive will not cut it. Sonically it is a nice sounding combo.
7-8 = 1425 ohms
1-3 = 22.5 ohms
4-6 = 35 ohms

Have you considered the Cinemags? They work great with both the 103 & 103R.
Hello Qman,
Indeed I have, however I got the impression that these "old guys" work even better. 15095's have x5 or x10 amplification, x5 will be sufficient and I will have x10 as an option. CineMag's are x18?, that is a bit too much, I don't like to get loud at 9 o'clock.
True. You need a lower gain somewhere either with your phono stage or line stage. You get 24dB or 29dB with the Cinemags. My gains add up to 20dB+24dB+29dB=73dB, but I really need to be around 63dB. I'm maxed @ 9 o'clock. My speakers are fairly high @ 97dB.
