Question about Class A

So I read all the time how awesome Class A Amps/Integrated's (SS and Tube) are.

I currently have a Vincent SV-500 Hybrid and feel it sounds really good.

But I have this itch now to hear what Class A would sound like and would it be a big difference to my current Vincent.

I wanted to ask what are some good Class A Integrated's that I could look into?

I know Pass Labs always comes up and for good reason but those might be a bit out of my budget.

I would say I can probably go to $3K new or used.

Sugden is another brand that I have researched a lot and the A21 retails for around $2500 and there is a dealer in Socal that carries it, so that one is tempting.

Vincent has the SV-237 MK II but I think that is only Class A for the 1st 10 watts into 8-ohms and I have 4-ohm speakers so I am not sure if that would give me any Class A magic. I am sure it would sound similar to my SV-500 but have more base extension.

Could you all recommend any other one's? I have been researching but haven't come across any (SS or Tube).

Thanks

The Speakers that I have are Martin Logan Motion 40’s and they are rated at 92db sensitivity.

With the Vincent, I think they sound great.

From what I have read and watched, 92db should be sensitive enough for lower wattage amps but I am realistic, I know with some lower wattage amps and Class A, I may get beautiful mid-range but lack in the bass department a bit.

But I am not hung up on huge bass so maybe wouldn’t be a big deal.

I have three Class A amplifiers....A Yamaha M45 that is both Class A and Class A/B with the push of a switch, A Tubes4HiFi ST120 Dynaco clone Tube Amplifier and a Pass Labs First Watt F5v2.....Here is what I hear... The tube amplifier is magnificent. Easily the best sounding amp to my ears in my room with my speakers (KEF LS50 Metas or Magnapan MMG).....Try as I may, I can’t really hear any difference with the Yamaha M45 either in A or A/B.....The First Watt sounds like the tube amplifier. Fast tight bass, great midrange/vocals....Just one heck of a great sounding amplifier......BUT, Does it sound better than an ADCOM 555 or a Sound Artist SA200ia? ..... Not sure....There are so many great sounding amplifiers out there...Both past and present vintage.

I wouldn’t get too hung up on the class of amplification since a good sounding amplifier is a good sounding amplifer...

Good amps can be had in every class. Concentrate on good amps not design.
