This Entre ET-300 from Soltear Acoustic, Japan, is one of the rarer and much sought after step up transformer. It has been highly rated for its smooth, warm and rich textured sound. Highs were a bit rolled off but the bottom end was full and substantial and the background is dark and quiet . Pairing with different MC cartridges reaped different results so individual preference is the order of the day when it all ends. The good news is that there is no “bad” pairing. Just differences in the type of enjoyment we had with different MC cartridges. So depending on the type of cartridges used, you can either use the pair that is rated for 3 ohm or lower or 40 ohm or lower. Output is fixed via its single pair of RCA out with a separate ground wire. If you are using a very exotic MC cartridge (which typically has very low outputs), the Entre ET-300 is a very affordable option to raise the performance of this cartridge. The unit is passive in design so there is no AC cord or the need to power it up.
Cosmetically, the unit looks really good. Just minor scuff marks here and there from use but nothing major. We don’t have the original box but will securely pack this for safe shipping.
