Hi 

I just thought I would say hello, share my thoughts and ask for a little advice. 

I discovered this site looking for amplifier reviews. I am hoping to buy something reasonably priced to run a turntable through and power my little speakers. The speakers are Blueroom Minipods which I have about fifteen years.  I bought them as nearfield monitors and really like the sound from them. Not too big, but suitable for my purposes (and mine are black which don't look as "toy-like" as the other colour options). The turntable is the ubiquitous Technics SL1210mk2 from my youthful DJ days. I've never really been into CDs or home cinema.

Based on reviews I have read here I will attempt to test the following but would appreciate your opinions and a little advice regarding their suitability.

Marantz PM6004     45w     €379

Rotel RA-10             40w      €430

Yamaha A-S500       85w     €380

Rega Brio-R             50w     €669

They are all integrated amps with a phono input and have roughly the same power (Yamaha excepted). They are all close enough in price (Rega excepted). The Yamaha is quite bulky but I really like the half-case size of the Rega and the feel-good factor of owning something made by a small independent company is appealing. Unfortunately the Rega doesn't have a headphone output which might be a problem.

Now my question. I don't really understand how speakers and amplifiers should be properly matched. If I remember correctly, my existing amplifier is 300w and I just tend to be careful that I don't turn it up too much. I have been on the website of the current Minipod manufacturer and the spec states the following

Amplifier requirement     10 - 100Watt at 8 Ω

Nominal impedance         4 Ω

Sensitivity                         90dB spl ( 2.83V / 1m )

All of the above amps fit comfortably within the 10 - 100watts but it is the Ω and sensitivity which has me confused. Any advice would be appreciated.
