Integrated as preamp?

Another installment in a series of newbie questions.

I had been using Arcam Alpha 8 integrated and power amps to biamp B&W 601S2 bookshelves. Recently, finally pulled trigger and upgraded speakers with oldies but goodies, very refined and revealing Thiel CS2s. They've only got two posts so no bi-amping option

So I now using the integrated as preamp and the power amp to drive the speakers. To my ear, Thiels sound great with this little 50W@8 ohm amp.

But Thiel experts on A'gon suggest more power would be much better.

Before I start hunting (and asking amp questions) can I continue to use the integrated, which has a nice phono stage, as a pre-amp? Will it handle, say, a 150-200 watt power amp? If not, how does one go about ensuring a pre-amp and amp match?

Yes, you can use the integrated as a preamp. If your current set-up sounds great to you ... stop and don't do anything else. Live with this set-up for a few months and begin to identify your likes and dislikes before considering any potential upgrades. This is one way to insure that you get the most out of an upgrade.

Best regards,

Why not?
My integrated as unbalanced outs. I currently use these outputs to a sub.

Rar1 is giving you excellent advice. Maverick18, I too would advise doing the same. You said:

Thanks, gentleman. Sage advice. I qualify my comments with great in comparison to the B&Ws. I suspect there is more, particularly on the low end, than my amp delivers.

Or maybe it is just the Thiels expose the limitations of my upstream gear (Rega P1) and (Sony SACD CE595, budget SACD multidisc that has gotten some bang for buck praise).

I have little to quibble with on analog side but some hit and miss with CDs that suddenly sound thin. Clearly, the speakers do expose poor recordings, too, because same songs on different CDs can sound quite different. May I ought to be looking to upgrade CD first.

To confess, the real problem is I have more than offset the cost of Thiels by selling my old stuff (stunning what used Bang & Olufsen cartridges fetch on ebay) so I am surprisingly sitting on a bit of cash and trying to figure best places to start a slow upgrade of rest of system. The amps, from reading other Thiel discussions, sounded like a good start.

I'm gonna think on it a bit.
