Solid state to tube

@ecpninja that's good.  I'd recommend following his advice him knowing the design and how different tubes respond.  Also good to see he recommended those particular rectifier tubes if you don't already have them installed now.  

 Modwright customer service is excellent. Congrats on your new pre.Enjoy

Tube preamp Solid state amp best combo JUMP ON IT ASAP!!!

I too was a SS guy for decades. Then a buddy brought over a tube integrated for me to try. I knew in the first few seconds that the sonics killed my Yamaha A-S3000 integrated. I thought the Yamaha was the last amp I was ever going to buy.

The amount you need to spend on a tube amp is determined by how demanding your speakers are. If your speakers are really efficient you can do very well with a low power tube amp which are more affordable than higher powered amps.

I bought my speakers after a demo because I loved how they sounded. I didn’t think too closely about efficient and less efficient speakers. After hearing the tube amp in my rig, I realized that if I wanted my speakers to reach their potential using a tube amp, I needed a ton of power because they are very inefficient. I thought my new PrimaLuna EVO400 power amp would have sufficient power but after several months of listening and listening to another system with Magico speakers, I knew my speakers still didn’t have enough power driving them. I contacted an expert who recommended NAT Audio Generator 805 mono blocks. My speakers are very happy now and so am I!

You won’t regret the switch to tubes!

So now that I have this modwright 9.0 tube preamp and I am liking what I hear so far. I might keep my YBA 1 dual mono amp and since I have always wanted to own a Nelson Pass product I may look on the used market for a pair of older Aleph 60's and see how they sound
