Spica TC-50 and amp advice

Those speakers are one of my favorites. They are an extremely musical midrange speaker. Actually, when you listen for awhile, you will really not miss the lows or highs...the mids are so good. Look to proven amp designs...Ayre, Audio Research, Conrad Johnson, etc. Use Anti-Cables for connections and you'll be happy.

Jaybo is right, "they are not fussy, so any quality integrated in your range will do just fine". Don't spend more than $350. A used integrated like Onkyo 9555 will be my first choice. You'll probably get very close result weather you spend $350 or $500.

It's amazing the different ampifiers used with the Spica TC 50's. I have had my best luck with a Dynaco ST 70 with Sound Valves input board. There are numerous other mods
done to it as well including a new power transformer, B+ power supply improvements. I'm also using a VanAlstine Super PAS 3si preamp and a Oppo 980 with Scott Nixon Tube DAC. I have a pair of TC60's also. I tried several solid state amps and they all sounded good but not as good as my
trusted Dyna. I have had many friends over and they were all impressed with the level of sound I had achieved.
I have tried to replace the Spicas with speakers that cost up to $5000 and the Spicas still remain. My room is 13 x 14 feet also. My first killer system was a pair of Spica TC 50's with the PS Audio IV a Spica Sub and SOTA TT with JS Technology Air Bearing Tonearm with a Sumiko Talisman S
LO cartridge. I embarassed a friends system that cost nearly $40k during the mid 80's. Vinyl was still king and I was enjoying it serving our country. Twenty Five years later I am on my 5th pair of TC50's and First pair of TC60's. I say tubes first and make sure the the power supply is designed properly. Good Luck and happy listening.

Nearly everyone missed that you have a PS Audio IV preamp which is still quite viable with separate power supply. There are several very good choices to include the Hafler 120, the best sounding Hafler amp. The Dynacos are great also.

This speaker is fairly simple to crossover upgrade and will sound much better with improved imaging, detail, quickness and extended bottom. They also need good stands.

I set up a system for my girlfriend based on TC-50s, but using "old" Linn electronics. Sounds great.
