    Pre Amp Upgrade

    Greetings all, I currently use a Fully Restored Dynaco PAS 2 tube amplifier. It's in line with my (all restored) Rek O Kut table, Citation 19 Amp, and Snell Type K speakers. I'm finding that the Pre amp is the "week spot" in my setup as I don't like the tone controls. I love the way the...

    Pre-amp for a Pioneer SX-737?

    Hi, I have a Pioneer SX-737 that works well except for the phono stage. Only one channel is functioning. I'm getting round this by plugging my turntable into the Aux input via an external phono pre-amp. It's only a budget one and I have to say, it doesn't sound as good as I remember the...

    Use Marantz 1060 as preamp for 2226B

    Hi all, First post here :) so I got myself a 2226B today and I also have a 1060 integrated. I compared the two and find the 1060 to sound better than the 2226B.

    Is the preamp in Sony TA-F555ES any good?

    I use Sony TA-F555ES amp, which I think was once a very good amp, and which I love myself as well. It's time to send it in for some revisions (the wheel to choose between A or B speakers needs to be checked), but there is another issue that I'm not sure I should have the guy look at: the phono...

The sound coming from the unit's main output was another matter. It had a nasty 60-cycle hum. Has anyone here who has owned this...

Out of these two, it seems the Yamaha would be the better choice. However, I've just recently acquired a Rotel RB-850 for $15 dollars, and it...

    Max distance from turntable to amp using RCAs
