Plinius SB 300 v Plinius SA 250 MK IV

Well my SA250 was a great amp. I have several sets of monoblock tubes and was a nice addition.

Hi,
i have the sa250 MK IV with the M 16 pre. I used to have the SA 100 mk 3, i agree with lak, ths 250 has a greater resuloution and The bass is more tight, a hugh improvment over the very good SA 100, so i believt the SB 300 will have the same character as the 250 and even furter. I wonder if anyone test XLR ic Aagainst unbalance rca. i use between the pre/amp rca (AQ LAPIZ) and wonder if it will be better to move to balance XLR.

Thanks in advance

TAS Opinion, in January issue, is that Plinius 301 SB and Spectron Musician III SE are extremely close to each other with Plinius slightly better in highs and Spectron is slightly better in bass.
The real difference is that Spectron is $1500 cheaper and twice lighter....
