I promised myself I'd never do this

You know the threads, where people ask for help matching this speaker to that amplifier (s)? Always seemed like wasted space in a lot of ways to me, but here I find myself pondering which way to go with my system. So, I break my own golden rule, and ask for your advice. The system: Oracle Delphi IV/SME345/Grado Reference, Magnum Dynalab Tuner, YBA CD Integre CD player, Audio Research SP14 Preamp, (2) Classe Audio DR8 amplifiers in bridged mode, Martin Logan Quest Z speakers bi-wired. Various quality IC's and power cords. I'm considering changing the amps, primarily due to a "live" listening room that would benefit from a more mellow sound, and the amps have more power than I'll ever need. Treating the room is out of the question, lawyers cost more than my rig. Naturally tubes come to mind, but the care and feeding of tube amps can be significant, solid state are plug and play and forget about 'em. I'd likely be looking to spend around $3k for a used amp, any suggestions on where to begin? Thanks in advance to any of you who take the time to respond, Jeff

Food for thought guys, thanks. I'm using Synergistic Research AC Master Coupler power cords on the amps, a high-end YBA cord on the CD, fixed cord on the SP14, and the Oracle table needs it's own cord. I'm using Transparent and MIT IC's. I've reduced toe in to almost nil, helped a little bit, but not enough yet. I'm using Bright Star bases under pre and CD, and a Seismic Sink under the 'table. I'm about to try out an isolation base from Cambridge, basically a metal shelf and you stick 5 of their little balls under it. Not sure what the balls are made of, probably some sort of rubber or sorbothane. Interesting that Paul feels the pre could be improved, I figured any tube preamp would add just enough bloom to offset the solid state amps. Oh, about 90% of my listening is primarily rock, both old and new. I'll mull this over some, thanks!

I have an ARC SP14 also and really like it, but remember it is a hybrid and the only tube is in the phono stage. So when your line stage is activated, you are solid state all the way. Move the Logans out into the room as far as you can and away from the side walls. If you can, use spikes to couple the speakers to the floor. Also experiment with toe-in and tilt back. Martin Logans are a pain sometimes to position correctly and suffer from the "venetion blind effect" to a certain degree.

The BAT VK30 does look like a good piece of gear, I'd need to find one with a phono stage. Scouring the web, haven't seen one for sale, but patience is a virtue. What balanced interconnect would you recoommend? I'd need 20ft run from pre to amp. Thanks, Jeff

jeff, don't overlook a melos preamp, if you can find one used. i got a melos music director a few months ago, & it's fantastic! unbelievable dynamics, great frequency extension, plenty of gain (the current owner of melos sez ~25% of melos owners use soundlab speakers - wery hard-to-drive), very low output impedence - especially for a tubed preamp. these were awailable in all-balanced configuration, which mine is, but i'm using it single-ended, & *still* have no problems, w/a 20' interconnect between the preamp & the x-over between my amps (electrocompaniets). these pre's were awailable w/a fono-stage, but i'm using a solid-state pentagon ps-3 w/it.

Sedond,I considered Melos at one time, but have heard through many 'philes that their customer service record was horrible. If Melos really does give poor support, regardless of how good their product is, I'd steer clear of them. Perhaps the new & improved owners of Melos will make an effort to clear their name? Any experiences you can pass along? As for audtioning new spekaers, I'd rather avoid that. Too obvious a component upgrade, whereas the wife has no idea what the rest of my stuff is. Besides, ML's set up right, are just plainly terrific, hard to beat. Thanks, I do appreciate your opinion. Jeff
