Can I use 7025 tubes instead of 12ax7
The 7025 is a direct 12AX7 substitute, the 5751 is not. In many cases the 5751 can be used in place of a 12AX7, but in some they sound positively horrible, as in a CAT preamp line stage I had. 
Sealed MOFI's on eBay
With the way that most MFSL reissues sound it is not surprising that no one opened them to listen to them. If they did they would find that the majority of them are sonically inferior to most original pressings. Like the poster above stated, the p... 
What's causing the highs to be rolled-off?
Could your tubes be going bad? Did you try switching them out? Are there any other symptoms? 
humming in my system
Another thing to try after going through all the procedures above is to get some wire and try grounding the chassis together in various arrangements and also to a known ground such as a screw on an AC outlet. Oftentimes your components can be at d... 
What am I missing???
I used to think this every time I saw and heard my friend Steve's stereo. He had Acapella Triolon Excalibur speakers driven by Audio Note Ongaku amps and T1000 preamp, Rockport System III Sirius turntable, DCS digital stack, etc. Then he sold it a... 
Tube Preamp Isolation suggestions
I still believe the old adage that you isolate your component from a less stable platform and couple it to a more stable platform. One thing that works really well is to use air to isolate components, i.e. small inner tubes. When I was in graduate... 
Best Small Speaker System You've ever Heard
The best small speakers I have heard are the Artemis EOS Signatures being driven by Gryphon electronics. Fantastic soundstaging, great tonality, and even reasonable bass from a small cabinet. They later also came with the bass modules, which reinf... 
help with s/n ratios of preamps and Moving Coil
Usually the lower MC signal-to-noise ratio is due to the additional gain required leading to a higher degree of amplification of noise inherent in the circuit. Oftentimes also, the clipping headroom for MC circuits is lower also. These may not mea... 
What started you on the merry go round?
Right after I graduated from high school I went over to my boss' house to listen to some music. He had a relatively inexpensive Lafayette Radio receiver and speakers, a Roberts reel-to-reel tape deck, and a Gerrard turntable, but I was hooked once... 
Joan Armatrading
If you like Joan you will probably also like Tracy Chapman and Edie Brickell, as well as Suzanne Vega and Marti Jones. All are good recordings as well. 
Upgrade suggestions from BAT VK-300xSE
I had Sophias, now WP7's, and ran them for a while with the BAT VK-500, then VK-600. Great bass and dynamics but no soundstage. My recommendation would be an ARC VT100 Mark III or Conrad-Johnson Premier 140. You will lose a little on the bottom en... 
Noise from phono. Help please.
I have had hum/noise problems in the past and have reduced it by trying various grounding schemes. Yes, the noise is probably RF and EMI being picked up by cables which act as antennas. It sounds as if your equipment is at different ground potenti... 
musical subwoofer recommendation for 2-ch
I have had experience with REL and JL Audio subwoofers. Both are highly regarded here on Audiogon. My REL Storm III subwoofer was connected to the high-level speaker outputs on my power amp, but could also be connected to the line-level outputs on... 
Anyone recommend a neutral tube amp?
I thought my Conrad-Johnson Premier 140 was quite neutral, although as others have said, it is nearly impossible to confuse it with a solid-state amp. The 140 was replaced by LP70S and LP140M amps, so I am not sure how they sound. 
worse entertainer or performer of all time??
Well, Yoko Ono, Britney Spears, and J-Lo definitely are vying for the worst. But here are mine:Worst group: Rolling Stones (also up for ugliest humans)Worst single artist: Elvis (also vying for worst actor)Never understood the attraction of these ...
