PrimaLuna ProLogue Two vs ProLogue Premium

If you can listen to them side by side and can hear a difference worth the money, then upgrade to the Premium.

If you cannot do a side by side comparison, I'd stay with the Prologue 2 and save your money until you can afford an upgrade that will make a big difference in the sound of your integrated. It is not worth the cost and trouble of selling your Prologue 2 and buying a different integrated for a small improvement in sound.

The Prologue 2 is a very good integrated. Stay with it until you get a chance to hear something you like better. The differences you read about in reviews are not always as noticeable as the review makes you think.

I hope all is well in Slovakia.

P.S. You can usually get the biggest improvement in sound for your money by upgrading your speakers, in my humble opinion. It is important that you listen to them first. It is best if you can listen to them in your home.

Most of us have tried to buy audio gear by reading reviews. Sometimes it works, sometimes it doesn't. It is usually better to listen first.
