Bottom Line:   
This review is for the A400.
Pioneer is a large company that depending on what you choose to pay offers from average amps at low prices all the way up to superb sounding units for a lot of money.
The A400 sounds amazing and had a low price tag in its day. Maybe Pioneer did it for marketing reasons and offered its expensive sound for litle money. Lucky us!
This amp has a very lively and exciting sound, and is highly recomended. Of course, as mentioned in previous posts, do not expect the sound quality of an MF A1, Arcam Delta 290, Quad 77, or Nait 5i from the A400. It is very good and you will enjoy it a lot. It's close to the top, but not at the top.

Bottom Line:   
This is an amplifier that is designed to play vinyl on, so you have to take your parents' old record player, Marantz, Dual or Technics turntable with a good pickup. I'll leave you to hear the amplifier's true nature. Enjoy.
I have a couple of B&W 601 S2`s, and two Pioneer CS-830 speakers connected. With midrange elements turned off, and highrange in half on the CS-830. B&W connected to High output and the Pioneere`s to low. Niiiiiice

Bottom Line:   
Had one of A400 for 3 years in early 2000s. It is a good amp, but that's it. It is not in the same league as something really gem like Audiolab 8000A or Arcam Delta290 Alpha9, not even a Marantz PM80.
It's just a good amp for what it worth.
Considering the age, be prepared to do some service job.

Bottom Line:   
Blown away by the A400X, when I read varing reviews comparing the A400 the chance to own a 400X came along and I grabbed it. The 400X when connected up to the right equipement can give you what your looking for depending on the type of music you like. I use my amp with a Marantz CD 67SE and Mission 731 Pro's, now not being the top of the line, music from them to me sounds impressive although it could do really well with a speaker upgrade or a good sub. You can biwire your speakers through th 400X as etxra speaker connection are available on this amp. This amp has very good imagery, clarity and I feel the sound becomes more fuller and richer when the amp is given a reasonable time to warm up, I think its a excellent amp in its class, its started me off with more appreciation for music reproduction and have no intentions of parting with it in the near future.

Bottom Line:   
I just had to write a review of my golden favourie amplifier the PIONERR A400 GTE (Tom Evans upgrade, made a significant improvement in all areas to the sound).

It really is a giant killer, those reviews are true! and the Tom Evans upgrade makes it even better - significantly so.

I have tried and compared this amp against other award amplifiers costing many times the price (including valves!) and this is a champion, its the one I have come back to and it is staying!

It is just so musical, foot tapping engaging and emotional to listen to. I will never change it.

But beware, feed it a poor signal, or a bright sound that you get from some cd players - including expensive ones from leading brands and it will sound bright. Feed it quality and that is what you get - real quality with whistles.

This is a Real Music maker with Emotion when fed a quality source. Back to the foot tapping for me!
