IMHO two A-75 (unbridged) would only make sense, if you opted for bi-amplification.

I have not heared yet of any speakers you could not fully control with two A-250 (unbridged).
In practice and with speakers with normal sensitivity (e.g. 90dB SPL @ 2.83V (1W)) you need much less power than 100W (@ 8 Ohms).
And do not forget that unlike virtually all other amps (including Macs) it's 200W @ 4Ohms, 400W at @ 2 Ohms and 800 W @ 1 Ohm; so plenty of power for low frequencies where usually a speaker's impedance drops low.

Or are your speakers capable of producing (and your ears of enduring) continuously more than 110 dB SPL?
(An average of 85 dB SPL is recommended to prevent your ears from becoming damaged!)

As someone who can't afford to purchase newer Accuphase but loves the brand, i was hoping for opinions on the C280v as a preamp today and in comparison with my current CX-260.

I do love that the CX-260 has remote volume and it's very smooth. It sounds great to me and looks beautiful with tons of inputs and 2 option board slots to keep up to date with DSD DACs(Currently have AD-10 and DAC-50, and i can try different power cables on it. I just wonder how much better a C280v would sound in comparison seeing as it was the ultimate pre amp of it's time and the CX-260 was likely not built to compete like that.

I use a P-360 power amp and it is from 91 and looks and performs flawless and outperformed my "newer" Mcintosh amps. So that gives me a bit of courage to spend big on older Accuphase preamps.

Thoughts?

According to Accuphase homepage the C-280V was launched 1990.12. Integrated phono preamp, no DAC, no remote control. Thirty years until today is a long time.
Its successors were C-290 (1993.11) and C-290V (1998.12) considered to be the last analog preamp (Mr. Ishizuka from German importer PIA and cofounder of Accuphase: 'the future is digital').
But the future remained analog with the C-2800 (2002.07), the first preamp featuring the newly developed AAVA analog volume control.

The C-260X (2001.04) is a multichannel home theater preamp. Contrary to the C-280V, the C-260X features current feedback technology, first introduced on C-290V. And in Stereo mode 2x 3 preamp modules work in parallel thus improving sound quality.

In 1991 the C-280V was the flagship model, but development never stopped, and every step was clearly audible.

The P-360 (1991.03) was the unbalanced version of the fully balanced P-800 (1988.07).

I used C-280V / P-800 on B&W Matrix 801 (Series 2 and Series 3) from 1991 til 2011.

My advice: only go as far back as you absolutely need to. And if you buy vintage, you should take the cost of an eventually needed overhaul (e.g. capacitors) into consideration.

Thanks for the information and advice, but do keep in mind even this old stuff was over 2k to over 3k USD which is already a lot to many including myself and all i can afford in the Accuphase brand. Are you suggesting then, to move on from Accuphase vintage and purchase new in the same price range of another brand because new would =more advanced and better?

I had no idea the P-360 was unbalanced. It sounds far better than the McIntosh over 10 years newer i owned so if there's a tier above, then id love to try Class A or a balanced Accuphase amp. C2800 was also another preamp i was looking at, but would require going for a less expensive power amp. It's just as i said, budget doesnt allow new Accuphase where each unit is in the 10-15k UDS range.

Follow up: would the total price of separates = "newer" model Accuphase integrated? Take the E-600 for example. Would it's preamp outperform my current preamp and would it's Class A built in amp outperform my P-360 or similar era Class A separate amps? Would an integrated the same price as vintage/older separates be the better route to go?

I cannot possibly be of any help to balance out your dreams with your budget.

Accuphase sound is addicting, and depending on your (and my) personal taste it is practically impossible to find equivalent new from other manufacturers in the price range of even vintage Accuphase.
IMHO not a viable solution.

Sorry I may not have been precise enough. The P-360 input and driver stages are of course balanced. But there is only a single output stage per channel. That's what I meant with 'unbalanced'.
(The P-800 has two identical output stages per channel; therefore is fully balanced input, driver and output stage.)
Fully balanced Stereo power amps like the P-800 are very rare in the Accuphase lineup. Mostly only the monoblock power amps are fully balanced.
I'm not surprised that you feel a P-360 driven by an Accuphase preamp of the same generation could outperform other brands.

Experience with Accuphase over the years showed, that synergy between preamp and power amp was at its best, when the units were from the same generation. Though changing the preamp does not necessarily mean you'd also have to change the power amp.
The matching preamp for a P-360 was the Stereo C-260. However your CX260 is 10 years younger.
I must admit I do not know anything about the sonic differences between CX-260 and C-260.
C-270V, C-280V might also be used, depending what is on the market.

Another option would be to go for a new integrated Accuphase (from E-280 up).

As I already mentioned in my previous post, going for a new (or used) Accuphase integrated might be an option.

Please keep in mind, that the Accuphase sound character has changed considerably in the past few years from somewhat reserved ('applied handbrake') to much more open and transparent.

IMHO an E-600 will outperform your current combo. However I cannot tell you, whether you will like its different sound character.

You will need to go out and listen for yourself.

I'd suggest you take your combo to an Accuphase dealer and start there to compare with an E-280 ( if this unit would be within your budget).
